Finding GCD of 27, 81, 24 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, 81) = 81
GCD(27, 81) = ( 27 x 81 ) / 81
GCD(27, 81) = 2187 / 81
GCD(27, 81) = 27
Step2:
Here we consider the GCD from the above i.e. 27 as first number and the next as 24
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(27, 24) = 216
GCD(27, 24) = ( 27 x 24 ) / 216
GCD(27, 24) = 648 / 216
GCD(27, 24) = 3
GCD of 27, 81, 24 is 3
