# What is the HCF of 2 and 4?

HCF of two or more numbers is the largest possible number which divides the given numbers exactly without any remainder.

## Answer: HCF of 2 and 4 is 2

Let us see how to find the HCF of 2 and 4

## Methods to Find HCF of 1 and 4

We can find the HCF by the following methods

- Prime factorization Method
- Long Division Method

### Method 1: HCF of 2 and 4 by Prime Factorization

Let us represent 2 and 4 as a product of its prime numbers

Common factors = 2, therefore, HCF of 2 and 4 is 2

### Method 2: HCF of 2 and 4 by Long Division Method

- Step 1: Divide 4 by 2 and check the remainder.
- Step 2: since we got the remainder as 0, two is the HCF of 2 and 4.
