The list of prime factors of all numbers are

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 637 are 7 x 7 x 13

Prime factors of 815 are 5 x 163

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

Given numbers are 988, 616, 637, 815

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

Apply this formula for all numbers.

Step1:

LCM(988, 616) = 152152

GCD(988, 616) = ( 988 x 616 ) / 152152

= 988 / 616

= 988

Step2:

LCM(4, 637) = 2548

GCD(4, 637) = ( 4 x 637 ) / 2548

= 4 / 637

= 4

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 988, 616, 637, 815 is 1
