Given numbers are 570, 291, 656, 493

The list of prime factors of all numbers are

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

Prime factors of 291 are 3 x 97

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

Prime factors of 493 are 17 x 29

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

Given numbers are 570, 291, 656, 493

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

Apply this formula for all numbers.

Step1:

LCM(570, 291) = 55290

GCD(570, 291) = ( 570 x 291 ) / 55290

= 570 / 291

= 570

Step2:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 570, 291, 656, 493 is 1
