# How do you find greatest factor?

## How do you find greatest factor?

To find the GCF of a set of numbers, list all the factors of each number. The greatest factor appearing on every list is the GCF. For example, to find the GCF of 6 and 15, first list all the factors of each number. Because 3 is the greatest factor that appears on both lists, 3 is the GCF of 6 and 15.

### How do you find the greatest common factor of 10?

To calculate the greatest common factor (GCF) of 10 and 20, we need to factor each number (factors of 10 = 1, 2, 5, 10; factors of 20 = 1, 2, 4, 5, 10, 20) and choose the greatest factor that exactly divides both 10 and 20, i.e., 10.

How do you find the highest common factor step by step?

How do I find the Highest Common Factor in Math?

1. Step 1: List the factors of two numbers.
2. Step 2: Identify the common factors of two numbers.
3. Step 3: HCF of two numbers is equal to the highest factor among the common factors of two numbers.

What is an example of greatest common factor?

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.

## How do you find the greatest common factor of two numbers?

To find the GCF of two numbers:

1. List the prime factors of each number.
2. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

### What is the greatest common factor for 10 and 12?

2
Answer: GCF of 10 and 12 is 2.

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).

What is the greatest common factor of 12 and 24?

12
GCF of 12 and 24 by Listing Common Factors There are 6 common factors of 12 and 24, that are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor of 12 and 24 is 12.
