Finding GCD of 76, 56, 30 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(76, 56) = 1064
GCD(76, 56) = ( 76 x 56 ) / 1064
GCD(76, 56) = 4256 / 1064
GCD(76, 56) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 30
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 30) = 60
GCD(4, 30) = ( 4 x 30 ) / 60
GCD(4, 30) = 120 / 60
GCD(4, 30) = 2
GCD of 76, 56, 30 is 2
