# What Are The Prime Factors Of 76

What are the prime factors of 76? Answer: 2, 19

The number 76 has 2 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. The biggest prime factor of 76 is 19. The smallest prime factor of 76 is 2.

## What Is The Factor Tree Of 76

How to use a factor tree to find the prime factors of 76? 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 we start with.

2 × 38
• Second step is to check the multiplication(of the first step) for numbers that are not primes.

We found 2 prime factors(2, 19) using the factor tree of 76. 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 76 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 76 Are Correct Answers

To know if we got the correct prime factors of 76 we have to get the prime factorization of 76 which is 2 * 2 * 19. Because when you multiply the primes of the prime factorization the answer has to be equal with 76.

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

## General Mathematical Properties Of Number 76

## Single Digit Properties For Number 76 Explained

• Integer 7 properties: Seven is an odd and defective number. The fourth prime, after 5 and before 11. Also called one of the primes of Mersenne, 7=2³-1. Known as one of the double prime integers, which is (7-1)÷2 still the same. 7 is the Cuban prime of the form (x³-y³)÷(x-y), x=y+1. Euclidian quantity 7=(2×3)+1. 7 is a Perrin, integer-free and congruent number. Smallest natural whose cube (343) is a palindrome. The second figure of Carol. A polygon with seven sides is called a heptagon. Part of the Pythagorean triad (7, 24, 25). Fifth of the succession of Lucas, after 4 and before 11. It is a palindrome in the binary system and a repeated number in the positional numbering system based on 6. In the numerical decimal system seven is a Colombian value.
• 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 76 has 2 primes. The prime factors of 76 are 2, 19. 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).
