Finding GCD of 78, 99, 54 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(78, 99) = 2574
GCD(78, 99) = ( 78 x 99 ) / 2574
GCD(78, 99) = 7722 / 2574
GCD(78, 99) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 54
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 54) = 54
GCD(3, 54) = ( 3 x 54 ) / 54
GCD(3, 54) = 162 / 54
GCD(3, 54) = 3
GCD of 78, 99, 54 is 3
