Given numbers are 642, 633, 331, 142

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 633 are 3 x 211

Prime factors of 331 are 331

Prime factors of 142 are 2 x 71

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

Given numbers are 642, 633, 331, 142

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

Apply this formula for all numbers.

Step1:

LCM(642, 633) = 135462

GCD(642, 633) = ( 642 x 633 ) / 135462

= 642 / 633

= 642

Step2:

LCM(3, 331) = 993

GCD(3, 331) = ( 3 x 331 ) / 993

= 3 / 331

= 3

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 642, 633, 331, 142 is 1
