Given numbers are 615, 364, 556, 972

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 556 are 2 x 2 x 139

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 615, 364, 556, 972

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

Apply this formula for all numbers.

Step1:

LCM(615, 364) = 223860

GCD(615, 364) = ( 615 x 364 ) / 223860

= 615 / 364

= 615

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 615, 364, 556, 972 is 1
