480, 120​

Answer 1

Step-by-step explanation:

We divide the bigger number by smaller one.

Divide smaller number in step 1 with remainder obtained in step 1.

Divide divisor of second step with remainder obtained in step 2.

We will continue this process till we get remainder zero and divisor obtained in end is the required H.C.F.

Let’s take few examples for this:

Example 1: Find the H.C.F. of 248 and 492?

To find the solution we will follow the following method i.e. we divide bigger number 492 by smaller one i.e. 248
