Given numbers are 130, 628, 657

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 628 are 2 x 2 x 157

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 130, 628, 657

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

Apply this formula for all numbers.

Step1:

LCM(130, 628) = 40820

GCD(130, 628) = ( 130 x 628 ) / 40820

= 130 / 628

= 130

Step2:

LCM(2, 657) = 1314

GCD(2, 657) = ( 2 x 657 ) / 1314

= 2 / 657

= 2

So, Greatest Common Divisor of 130, 628, 657 is 1
