Given numbers are 637, 342, 368, 405

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

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

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

Given numbers are 637, 342, 368, 405

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

Apply this formula for all numbers.

Step1:

LCM(637, 342) = 217854

GCD(637, 342) = ( 637 x 342 ) / 217854

= 637 / 342

= 637

Step2:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 637, 342, 368, 405 is 1
