The list of prime factors of all numbers are

Prime factors of 137 are 137

Prime factors of 646 are 2 x 17 x 19

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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 137, 646, 405, 142

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

Apply this formula for all numbers.

Step1:

LCM(137, 646) = 88502

GCD(137, 646) = ( 137 x 646 ) / 88502

= 137 / 646

= 137

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 137, 646, 405, 142 is 1
