Answer:

The answer to your question is 105

Explanation:

To get the least common factor dividing both numbers by the prime numbers starting from 2.

But these numbers are not multiples of 2, try 3

21 105 3

These numbers are not multiples of 3 let's try 5

7 35 5

These numbers are multiples of 7 7 7 7

1 1

The LCM is the product of the prime numbers = 3 x 5 x 7 = 105
