Given numbers are 642, 372, 251, 102

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 251 are 251

Prime factors of 102 are 2 x 3 x 17

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

Given numbers are 642, 372, 251, 102

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

Apply this formula for all numbers.

Step1:

LCM(642, 372) = 39804

GCD(642, 372) = ( 642 x 372 ) / 39804

= 642 / 372

= 642

Step2:

LCM(6, 251) = 1506

GCD(6, 251) = ( 6 x 251 ) / 1506

= 6 / 251

= 6

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 642, 372, 251, 102 is 1
