Finding GCD of 27, 72, 57 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(27, 72) = 216
GCD(27, 72) = ( 27 x 72 ) / 216
GCD(27, 72) = 1944 / 216
GCD(27, 72) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 57) = 171
GCD(9, 57) = ( 9 x 57 ) / 171
GCD(9, 57) = 513 / 171
GCD(9, 57) = 3
GCD of 27, 72, 57 is 3
