## How do I find a prime factor?

Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder.

Then divide by 3, 5, 7, etc.

until the only numbers left are prime numbers.

Step 2: Write the number as a product of prime numbers..

## What is the GCF of 24 and 84?

We can see that 24 and 84 have 2 x 2 x 3 in common, therefore, 12 is the greatest common factor.

## What is prime factor example?

A factor that is a prime number. In other words: any of the prime numbers that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers). See: Prime Number. Prime Factorization.

## What is the GCF of 28 and 36?

We found the factors and prime factorization of 28 and 36. The biggest common factor number is the GCF number. So the greatest common factor 28 and 36 is 4.

## What is the prime factorization of 80?

80 = 1 x 80, 2 x 40, 4 x 20, 5 x 16, and 8 x 10. Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80. Prime factorization: 80 = 2 x 2 x 2 x 2 x 5 which can also be written 80 = 2⁴ x 5.

## What is the prime factorization 225?

The orange divisor(s) above are the prime factors of the number 225. If we put all of it together we have the factors 3 x 3 x 5 x 5 = 225. It can also be written in exponential form as 32 x 52.

## What is prime factor?

Prime factors are factors of a number that are, themselves, prime numbers. There are many methods to find the prime factors of a number, but one of the most common is to use a prime factor tree.

## What’s the GCF of 52 and 78?

26The GCF of 52 and 78 is 26.

## What is a prime factor of 60?

Example 5. Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.
