Lets see how to find the LCM of 20 and 35


Least Common Multiple is the smallest number that divides both the numbers, 20 and 35 exactly.

Look at the two methods to find LCM(20, 35) explained below.

Methods to Find LCM of 20 and 35

Let us use the following methods to find the LCM of 20 and 35

  • Listing the Multiples
  • Common Division

LCM of 6 and 8 by Listing Method

In this method, we list the first few multiples(20, 35) and identify the common multiples.

The least among the common multiples is the LCM(20, 35)

LCM(20, 35) by Listing Method

So, LCM of 20 and 35 is 140

LCM(20, 35) by Common Division Method

In this division method, we divide the numbers simultaneously with prime numbers and stop it when we don't have a prime number to divide the given numbers.

LCM(20, 35) by Common Division Method

By this method, we get LCM(20, 35) = 140

Irrespective of the method, the solution to our question LCM(20, 35) is the same.

Therefore, LCM(20, 35) is 140
