Finding GCD of 33, 72, 39 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(33, 72) = 792
GCD(33, 72) = ( 33 x 72 ) / 792
GCD(33, 72) = 2376 / 792
GCD(33, 72) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 39
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 39) = 39
GCD(3, 39) = ( 3 x 39 ) / 39
GCD(3, 39) = 117 / 39
GCD(3, 39) = 3
GCD of 33, 72, 39 is 3
