# What Are The Prime Factors Of 16

What are the prime factors of 16? Answer: 2

The number 16 has 1 prime factors. Primes can only have two factors(1 and itself) and only be divisible by those two factors. Any figure where this rule applies can be called a prime factor.

## What Is The Factor Tree Of 16

How to use a factor tree to find the prime factors of 16? A factor tree is a diagram that organizes the factoring process.

First step is to find two numbers that when multiplied together equal the number 16.

We found 1 prime factors(2) using the factor tree of 16. Now let us explain the process to solving factor trees in more detail. Our goal is to find all prime factors of a given whole number. In each step of our factor tree diagram for 16 we always checked both multiplication numbers if they were primes or not. If one or both of the integers are not prime numbers then this means that we will have to make diagrams for them too. This process continues until only prime numbers are left.

Remember that often a factor tree for the same integer can be solved in more than one correct way! An example of this is the figure 12 where 2*6=12 and 4*3=12. The primes of a factor tree for 12 are the same regardles if we start the factor tree with 2*6 or 4*3.

## How To Verify If Prime Factors Of 16 Are Correct Answers

To know if we got the correct prime factors of 16 we have to get the prime factorization of 16 which is 2 * 2 * 2 * 2. Because when you multiply the primes of the prime factorization the answer has to be equal with 16.

After having checked the prime factorization we can now safely say that we got all prime factors.

## General Mathematical Properties Of Number 16

16 is a composite number. 16 is a composite number, because it has more divisors than 1 and itself. This is an even number. 16 is an even number, because it can be divided by 2 without leaving a comma spot. This also means that 16 is not an odd number. When we simplify Sin 16 degrees we get the value of sin(16)=-0.28790331666507. Simplify Cos 16 degrees. The value of cos(16)=-0.95765948032338. Simplify Tan 16 degrees. Value of tan(16)=0.3006322420239. When converting 16 in binary you get 10000. Converting decimal 16 in hexadecimal is 10. The square root of 16=4. The cube root of 16=2.5198420997897. Square root of √16 simplified is 15. All radicals are now simplified and in their simplest form. Cube root of ∛16 simplified is 2∛2. The simplified radicand no longer has any more cubed factors.

## Single Digit Properties For Number 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 All Prime Factors Of A Number

We found that 16 has 1 primes. The prime factors of 16 are 2. We arrived to this answer by using the factor tree. However we could have also used upside down division to get the factorization primes. There are more that one method to factorize a integer.

## List of divisibility rules for finding prime factors faster

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

Rule 2: If the sum of digits of a integer is divisible by 3 then the figure is also divisible by 3 and 3 is a prime factor(example: the digits of 12 are 1 and 2 so 1+2=3 and 3 is divisible by 3, meaning that 12 is divisible by 3). The same logic also works for 9.

Rule 3: If the last two digits of a number are 00 then this integer is divisible by 4(example: we know that 124=100+24 and 100 has two zeros in the end making it divisible with 4. We also know that 4 is divisible with 24). 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 number is 0 or 5 then 5 it is divisible by 5.

Rule 5: All integers that are divisible by both 2 and 3 are also divisible by 6. This is logical because 2*3=6.

## What Are Prime Factors Of A Number?

All numbers that are only divisible by one and itself are called prime factors in mathematics. A prime factor is a figure that has only two factors(one and itself).
