Finding GCD of 642, 638, 95 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(642, 638) = 204798
GCD(642, 638) = ( 642 x 638 ) / 204798
GCD(642, 638) = 409596 / 204798
GCD(642, 638) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 95
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 95) = 190
GCD(2, 95) = ( 2 x 95 ) / 190
GCD(2, 95) = 190 / 190
GCD(2, 95) = 1
GCD of 642, 638, 95 is 1
