What are the steps to find the greatest common factor?

Here’s how to find the GCF of a set of numbers using prime factorization:

1. List the prime factors of each number.
2. Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
3. Multiply all the circled numbers. The result is the GCF.

How do you find the greatest common factor of 36?

To calculate the greatest common factor (GCF) of 36 and 54, we need to factor each number (factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36; factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54) and choose the greatest factor that exactly divides both 36 and 54, i.e., 18.

What is the greatest common factor GCF GCF of 27 and 36 enter your answer in the box?

Answer: GCF of 27 and 36 is 9. The greatest common factor (gcf), or highest common factor (hcf), of two or more integers (at least one of which is not zero), is the largest positive integer that divides the numbers without a remainder. GCF (7,56) = 7.

How do you find the greatest common divisor?

Finding Greatest Common Divisor by LCM Method

1. Step 1: Find the product of a and b.
2. Step 2: Find the least common multiple (LCM) of a and b.
3. Step 3: Divide the values obtained in Step 1 and Step 2.
4. Step 4: The obtained value after division is the greatest common divisor of (a, b).
