## What is the greatest common factor of 4 and 10?

Answer: GCF of 4 and 10 is 2.

## What is the LCM 4 and 10?

20

The LCM of 4 and 10 is 20. To find the LCM (least common multiple) of 4 and 10, we need to find the multiples of 4 and 10 (multiples of 4 = 4, 8, 12, 16 . . . .

**What does GCF mean in fractions?**

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. GCF is often used to find common denominators.

**What is the greatest factor of 10?**

Factors of 10 are the list of integers that we can split evenly into 10. There are overall 4 factors of 10 i.e. 1, 2, 5 and 10 where 10 is the biggest factor.

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

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

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

### What is the greatest common factor between 10 and 5?

5

The GCF of 5 and 10 is 5.

**What is the greatest common factor of 10 and 15?**

GCF of 10 and 15 by Listing Common Factors Therefore, the greatest common factor of 10 and 15 is 5.

**What is the LCM and HCF of 4 and 10?**

Example 1: Find the HCF of 4 and 10, if their LCM is 20. Therefore, the highest common factor of 4 and 10 is 2. Example 2: Find the highest number that divides 4 and 10 exactly.

## What are the multiples of 4 and 10?

Explanation:

- multiples of 10:{10,20,30,40,50,…}
- multiples 4:{4,8,12,16,20,24,28,32,36,40,…}
- common multiples {20,40,…. }

## How do I find the greatest common 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.
