Given numbers are 858, 721, 255, 572

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 721 are 7 x 103

Prime factors of 255 are 3 x 5 x 17

Prime factors of 572 are 2 x 2 x 11 x 13

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

Given numbers are 858, 721, 255, 572

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

Apply this formula for all numbers.

Step1:

LCM(858, 721) = 618618

GCD(858, 721) = ( 858 x 721 ) / 618618

= 858 / 721

= 858

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

So, Greatest Common Divisor of 858, 721, 255, 572 is 1
