Given numbers are 656, 747, 786, 570

The list of prime factors of all numbers are

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

Prime factors of 747 are 3 x 3 x 83

Prime factors of 786 are 2 x 3 x 131

Prime factors of 570 are 2 x 3 x 5 x 19

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

Given numbers are 656, 747, 786, 570

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

Apply this formula for all numbers.

Step1:

LCM(656, 747) = 490032

GCD(656, 747) = ( 656 x 747 ) / 490032

= 656 / 747

= 656

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 656, 747, 786, 570 is 1
