# What Is The Prime Factorization Of 16

What is the prime factorization of 16? Answer: 2 * 2 * 2 * 2

The prime factorization of 16 has 4 prime factors. If you multiply all primes in the factorization together then 16=2 * 2 * 2 * 2. Prime factors can only have two factors(1 and itself) and only be divisible by those two factors. Any number where this rule applies can be called a prime factor. The biggest prime factor of 16 is 2. The smallest prime factor of 16 is 2.

## How To Write 16 As A Product Of Prime Factors

How to write 16 as a product of prime factors or in exponential notation? First we need to know the prime factorization of 16 which is 2 * 2 * 2 * 2. Next we add all numbers that are repeating more than once as exponents of these numbers.

Using exponential notation we can write 16=24

For clarity all readers should know that 16=2 * 2 * 2 * 2=24 this index form is the right way to express a number as a product of prime factors.

## Prime Factorization Of 16 With Upside Down Division Method

Prime factorization of 16 using upside down division method. Upside down division gives visual clarity when writing it on paper. It works by dividing the starting number 16 with its smallest prime factor(a figure that is only divisible with itself and 1). Then we continue the division with the answer of the last division. We find the smallest prime factor for each answer and make a division. We are essentially using successive divisions. This continues until we get an answer that is itself a prime factor. Then we make a list of all the prime factors that were used in the divisions and we call it prime factorization of 16.

2|16 We divide 16 with its smallest prime factor, which is 2
2|8 We divide 8 with its smallest prime factor, which is 2
2|4 We divide 4 with its smallest prime factor, which is 2
2 The division of 2/4=2. 2 is a prime factor. Prime factorization is complete

The solved solution using upside down division is the prime factorization of 16=2 * 2 * 2 * 2. Remember that all divisions in this calculation have to be divisible, meaning they will leave no remainder.

## Single Digit Properties For 16 Explained

• Integer 1 properties: 1 is an odd figure. In set theory, the 1 is constructed starting from the empty set obtaining {∅}, whose cardinality is precisely 1. It is the neutral element of multiplication and division in the sets of natural, integer, rational and real numbers. The first and second digit of the Fibonacci sequence(before 2). Second to the succession of Lucas(after 2). First element of all the successions of figured numbers. One is a part of the Tetranacci Succession. 1 is a number of: Catalan, Dudeney, Kaprekar, Wedderburn-Etherington. It is strictly non-palindrome, integer-free, first suitable digit, first issue of Ulam and the first centered square. The first term of the succession of Mian-Chowla. Complete Harshad, which is a number of Harshad in any expressed base. 1 is the first highly totest integer and also the only odd number that is not non-tottering.
• Integer 6 properties: 6 is even and a composite, with the following divisors:1, 2, 3, 6. Also called perfect number since the sum of the divisors(excluding itself) is 6. The first perfect figure, the next ones are 28 and 496. Six is highly a composed, semiprimo, congruent, scarcely total, Ulam, Wedderburn-Etherington, multi-perfect, integer-free number. Complete Harshad, which is a quantity of Harshad in any expressed base. The factorial of 3 and a semi-perfect digit. The third triangular and the first hexagonal value. All perfect even amounts are triangular and hexagonal. Six is the smallest amount different from 1 whose square (36) is triangular(the next in the line that enjoys this property is 35). Strictly a non-palindrome. A numeral is divisible by 6 if and only if it is divisible by both 2 and 3. Part of the Pythagorean triple (6, 8, 10). Being the product of the first two primes (6=2×3), it is a primitive. In the positional numbering system based on 5 it is a repeated number. An oblong, of the form n(n+1).

## Finding Prime Factorization Of A Number

The prime factorization of 16 contains 4 primes. The prime factorization of 16 is and equals 2 * 2 * 2 * 2. This answer was calculated using the upside down division method. We could have also used other methods such as a factor tree to arrive to the same answer. The method used is not important. What is important is to correctly solve the solution.

## List of divisibility rules for finding prime factors faster

Knowing these divisibility rules will help you find primes more easily. Finding prime factors faster helps you solve prime factorization faster.

Rule 1: If the last digit of a number is 0, 2, 4, 6 or 8 then it is an even integer. All even integers are divisible by 2.

Rule 2: If the sum of digits of a number is divisible by 3 then the figure is also divisible by 3 and 3 is a prime factor(example: the digits of 102 are 1, 0 and 2 so 1+0+2=3 and 3 is divisible by 3, meaning that 102 is divisible by 3). The same logic works also for number 9.

Rule 3: If the last two digits of a number are 00 then this number is divisible by 4(example: we know that 212=200+12 and 200 has two zeros in the end making it divisible with 4. We also know that 4 is divisible with 12). In order to use this rule to it's fullest it is best to know multiples of 4.

Rule 4: If the last digit of a integer is 0 or 5 then it is divisible by 5. We all know that 2*5=10 which is why the zero is logical.

Rule 5: All numbers that are divisible by both 2 and 3 are also divisible by 6. This makes much sense because 2*3=6.

## What Is Prime Factorization Of A Number?

In mathematics breaking down a composite number(a positive integer that can be the sum of two smaller numbers multiplied together) into a multiplication of smaller figures is called factorization. When the same process is continued until all numbers have been broken down into their prime factor multiplications then this process is called prime factorization.

Using prime factorization we can find all primes contained in a number.
