Given numbers are 651, 697, 580, 656

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 697 are 17 x 41

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 651, 697, 580, 656

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

Apply this formula for all numbers.

Step1:

LCM(651, 697) = 453747

GCD(651, 697) = ( 651 x 697 ) / 453747

= 651 / 697

= 651

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 651, 697, 580, 656 is 1
