Finding GCD of 12, 63, 75 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(12, 63) = 252
GCD(12, 63) = ( 12 x 63 ) / 252
GCD(12, 63) = 756 / 252
GCD(12, 63) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 75
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 75) = 75
GCD(3, 75) = ( 3 x 75 ) / 75
GCD(3, 75) = 225 / 75
GCD(3, 75) = 3
GCD of 12, 63, 75 is 3
