Given numbers are 142, 156, 639, 557

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 639 are 3 x 3 x 71

Prime factors of 557 are 557

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

Given numbers are 142, 156, 639, 557

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

Apply this formula for all numbers.

Step1:

LCM(142, 156) = 11076

GCD(142, 156) = ( 142 x 156 ) / 11076

= 142 / 156

= 142

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 142, 156, 639, 557 is 1
