Given numbers are 130, 557, 315, 788

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 557 are 557

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 788 are 2 x 2 x 197

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

Given numbers are 130, 557, 315, 788

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

Apply this formula for all numbers.

Step1:

LCM(130, 557) = 72410

GCD(130, 557) = ( 130 x 557 ) / 72410

= 130 / 557

= 130

Step2:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

Step3:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

So, Greatest Common Divisor of 130, 557, 315, 788 is 1
