Given numbers are 615, 547, 642, 353

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 547 are 547

Prime factors of 642 are 2 x 3 x 107

Prime factors of 353 are 353

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

Given numbers are 615, 547, 642, 353

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

Apply this formula for all numbers.

Step1:

LCM(615, 547) = 336405

GCD(615, 547) = ( 615 x 547 ) / 336405

= 615 / 547

= 615

Step2:

LCM(1, 642) = 642

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

= 1 / 642

= 1

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 615, 547, 642, 353 is 1
