Given Input Data is 56, 57, 84
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 56 is 2 x 2 x 2 x 7
Prime Factorization of 57 is 3 x 19
Prime Factorization of 84 is 2 x 2 x 3 x 7

Finding GCD of 56, 57, 84 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(56, 57) = 3192
GCD(56, 57) = ( 56 x 57 ) / 3192
GCD(56, 57) = 3192 / 3192
GCD(56, 57) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 84
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 84) = 84
GCD(1, 84) = ( 1 x 84 ) / 84
GCD(1, 84) = 84 / 84
GCD(1, 84) = 1
GCD of 56, 57, 84 is 1
