Finding GCD of 76, 78, 90 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, 78) = 2964
GCD(76, 78) = ( 76 x 78 ) / 2964
GCD(76, 78) = 5928 / 2964
GCD(76, 78) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 90
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 90) = 90
GCD(2, 90) = ( 2 x 90 ) / 90
GCD(2, 90) = 180 / 90
GCD(2, 90) = 2
GCD of 76, 78, 90 is 2
