Given numbers are 422, 596, 780, 691

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 596 are 2 x 2 x 149

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 691 are 691

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

Given numbers are 422, 596, 780, 691

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

Apply this formula for all numbers.

Step1:

LCM(422, 596) = 125756

GCD(422, 596) = ( 422 x 596 ) / 125756

= 422 / 596

= 422

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 691) = 1382

GCD(2, 691) = ( 2 x 691 ) / 1382

= 2 / 691

= 2

So, Greatest Common Divisor of 422, 596, 780, 691 is 1
