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)
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.
By this method, we get LCM(20, 35) = 140
Irrespective of the method, the solution to our question LCM(20, 35) is the same.
