Six interesting greatest common factor word problems you can give to your students to tease them. A cell phone company produces 40 defective phones out of every 5000 phones. Another cell phone company produces 30 defective phones out of every 6000 phones.

## How do you solve GCF problems?

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.

What is the example of GCF?

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

### What is the GCF of 20 24 and 40?

Answer: The common factors for 20,24,40 20 , 24 , 40 are 1,2,4 1 , 2 , 4 . The GCF (HCF) of the numerical factors 1,2,4 1 , 2 , 4 is 4 .

### What is the GCF of 18 and 24?

6
The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

What’s the GCF of 3 and 18?

3
Answer: GCF of 3 and 18 is 3.

## What is the GCF of 3 and 6?

Answer: GCF of 3 and 6 is 3.

## What is the GCF of 20 24 and 40 * 1 point?

What is the GCF of 24 and 20?

4
Answer: GCF of 20 and 24 is 4.
