Given numbers are 130, 425, 815, 157

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 425 are 5 x 5 x 17

Prime factors of 815 are 5 x 163

Prime factors of 157 are 157

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

Given numbers are 130, 425, 815, 157

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

Apply this formula for all numbers.

Step1:

LCM(130, 425) = 11050

GCD(130, 425) = ( 130 x 425 ) / 11050

= 130 / 425

= 130

Step2:

LCM(5, 815) = 815

GCD(5, 815) = ( 5 x 815 ) / 815

= 5 / 815

= 5

Step3:

LCM(5, 157) = 785

GCD(5, 157) = ( 5 x 157 ) / 785

= 5 / 157

= 5

So, Greatest Common Divisor of 130, 425, 815, 157 is 1
