Given Input Data is 252, 315, 57, 515

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 57 is 3 x 19

Prime Factorization of 515 is 5 x 103

The above numbers do not have any common prime factor. So GCD is 1

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(252, 315) = 1260

GCD(252, 315) = ( 252 x 315 ) / 1260

GCD(252, 315) = 79380 / 1260

GCD(252, 315) = 63

Step2:

Here we consider the GCD from the above i.e. 63 as first number and the next as 57

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(63, 57) = 1197

GCD(63, 57) = ( 63 x 57 ) / 1197

GCD(63, 57) = 3591 / 1197

GCD(63, 57) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 515

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

GCD(3, 515) = 1545 / 1545

GCD(3, 515) = 1

GCD of 252, 315, 57, 515 is 1
