Given numbers are 568, 870, 457, 644

The list of prime factors of all numbers are

Prime factors of 568 are 2 x 2 x 2 x 71

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 457 are 457

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 568, 870, 457, 644

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

Apply this formula for all numbers.

Step1:

LCM(568, 870) = 247080

GCD(568, 870) = ( 568 x 870 ) / 247080

= 568 / 870

= 568

Step2:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 568, 870, 457, 644 is 1
