Given numbers are 615, 657, 422, 814

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 657 are 3 x 3 x 73

Prime factors of 422 are 2 x 211

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 615, 657, 422, 814

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

Apply this formula for all numbers.

Step1:

LCM(615, 657) = 134685

GCD(615, 657) = ( 615 x 657 ) / 134685

= 615 / 657

= 615

Step2:

LCM(3, 422) = 1266

GCD(3, 422) = ( 3 x 422 ) / 1266

= 3 / 422

= 3

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 615, 657, 422, 814 is 1
