Finding GCD of 32, 64, 20 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(32, 64) = 64

GCD(32, 64) = ( 32 x 64 ) / 64

GCD(32, 64) = 2048 / 64

GCD(32, 64) = 32

Step2:

Here we consider the GCD from the above i.e. 32 as first number and the next as 20

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(32, 20) = 160

GCD(32, 20) = ( 32 x 20 ) / 160

GCD(32, 20) = 640 / 160

GCD(32, 20) = 4

GCD of 32, 64, 20 is 4
