The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 381 are 3 x 127

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 634 are 2 x 317

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

Given numbers are 791, 381, 156, 634

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

Apply this formula for all numbers.

Step1:

LCM(791, 381) = 301371

GCD(791, 381) = ( 791 x 381 ) / 301371

= 791 / 381

= 791

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 791, 381, 156, 634 is 1
