Given numbers are 639, 451, 642, 101

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 451 are 11 x 41

Prime factors of 642 are 2 x 3 x 107

Prime factors of 101 are 101

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

Given numbers are 639, 451, 642, 101

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

Apply this formula for all numbers.

Step1:

LCM(639, 451) = 288189

GCD(639, 451) = ( 639 x 451 ) / 288189

= 639 / 451

= 639

Step2:

LCM(1, 642) = 642

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

= 1 / 642

= 1

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 639, 451, 642, 101 is 1
