Answer: LCM of 20 and 36 is 180.
Let us see how to find the LCM(20,36).
Explanation:
Least Common Multiple of 20 and 36 is the smallest number which is exactly divisible by 20 and 36.
We will explain two methods to find LCM of 20 and 36.
Methods to Find LCM of 20 and 36

Method 1: LCM of 20 and 36 by Common Division Method
In this division method, we divide the 20 and 36 simultaneously with prime numbers and stop it when we don't have a prime number to divide both 20 and 36

Method 2: LCM of 20 and 36 by Formula
The formula of LCM is LCM (a, b) = (a × b) / GCF (a, b)
The Greatest Common Factor of (20, 36) = 4.
So, GCF (20, 36) = 4
Therefore, LCM of 20 and 36 = (20 × 36) / 4 = 720/4 = 180
Therefore, LCM of 20 and 36 is 180
