Finding GCD of 48, 42, 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(48, 42) = 336
GCD(48, 42) = ( 48 x 42 ) / 336
GCD(48, 42) = 2016 / 336
GCD(48, 42) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 87
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 87) = 174
GCD(6, 87) = ( 6 x 87 ) / 174
GCD(6, 87) = 522 / 174
GCD(6, 87) = 3
GCD of 48, 42, 87 is 3
