## 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?

- Step 1: List the factors of two numbers.
- Step 2: Identify the common factors of two numbers.
- 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:

- List the prime factors of each number.
- 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

- Step 1: Find the product of a and b.
- Step 2: Find the least common multiple (LCM) of a and b.
- Step 3: Divide the values obtained in Step 1 and Step 2.
- 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.
