Given numbers are 656, 644, 553, 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 644 are 2 x 2 x 7 x 23

Prime factors of 553 are 7 x 79

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, 644, 553, 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, 644) = 105616

GCD(656, 644) = ( 656 x 644 ) / 105616

= 656 / 644

= 656

Step2:

LCM(4, 553) = 2212

GCD(4, 553) = ( 4 x 553 ) / 2212

= 4 / 553

= 4

Step3:

LCM(1, 570) = 570

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

= 1 / 570

= 1

So, Greatest Common Divisor of 656, 644, 553, 570 is 1
