Given numbers are 316, 252, 57, 642

The list of prime factors of all numbers are

Prime factors of 316 are 2 x 2 x 79

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 57 are 3 x 19

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 316, 252, 57, 642

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(316, 252) = 19908

GCD(316, 252) = ( 316 x 252 ) / 19908

= 316 / 252

= 316

Step2:

LCM(4, 57) = 228

GCD(4, 57) = ( 4 x 57 ) / 228

= 4 / 57

= 4

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 316, 252, 57, 642 is 1
