Given numbers are 791, 310, 175, 640

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 310 are 2 x 5 x 31

Prime factors of 175 are 5 x 5 x 7

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, 310, 175, 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, 310) = 245210

GCD(791, 310) = ( 791 x 310 ) / 245210

= 791 / 310

= 791

Step2:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 791, 310, 175, 640 is 1
