Finding GCD of 239, 638, 87 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(239, 638) = 152482
GCD(239, 638) = ( 239 x 638 ) / 152482
GCD(239, 638) = 152482 / 152482
GCD(239, 638) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 87
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
GCD(1, 87) = 87 / 87
GCD(1, 87) = 1
GCD of 239, 638, 87 is 1
