Given numbers are 228, 645, 642, 502

The list of prime factors of all numbers are

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 645 are 3 x 5 x 43

Prime factors of 642 are 2 x 3 x 107

Prime factors of 502 are 2 x 251

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

Given numbers are 228, 645, 642, 502

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

Apply this formula for all numbers.

Step1:

LCM(228, 645) = 49020

GCD(228, 645) = ( 228 x 645 ) / 49020

= 228 / 645

= 228

Step2:

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

= 3 / 642

= 3

Step3:

LCM(3, 502) = 1506

GCD(3, 502) = ( 3 x 502 ) / 1506

= 3 / 502

= 3

So, Greatest Common Divisor of 228, 645, 642, 502 is 1
