The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 498 are 2 x 3 x 83

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 791, 770, 498, 640

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

Apply this formula for all numbers.

Step1:

LCM(791, 770) = 87010

GCD(791, 770) = ( 791 x 770 ) / 87010

= 791 / 770

= 791

Step2:

LCM(7, 498) = 3486

GCD(7, 498) = ( 7 x 498 ) / 3486

= 7 / 498

= 7

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 791, 770, 498, 640 is 1
