Given numbers are 631, 130, 615, 660

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 130 are 2 x 5 x 13

Prime factors of 615 are 3 x 5 x 41

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 631, 130, 615, 660

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

Apply this formula for all numbers.

Step1:

LCM(631, 130) = 82030

GCD(631, 130) = ( 631 x 130 ) / 82030

= 631 / 130

= 631

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 631, 130, 615, 660 is 1
