Given Input Data is 646, 908, 287, 252

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 908 is 2 x 2 x 227

Prime Factorization of 287 is 7 x 41

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

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(646, 908) = 293284

GCD(646, 908) = ( 646 x 908 ) / 293284

GCD(646, 908) = 586568 / 293284

GCD(646, 908) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 287

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

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

GCD(2, 287) = 574 / 574

GCD(2, 287) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 252

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

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

GCD(1, 252) = 252 / 252

GCD(1, 252) = 1

GCD of 646, 908, 287, 252 is 1
