Given numbers are 858, 861, 320, 573

The list of prime factors of all numbers are

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

Prime factors of 861 are 3 x 7 x 41

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 573 are 3 x 191

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

Given numbers are 858, 861, 320, 573

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

Apply this formula for all numbers.

Step1:

LCM(858, 861) = 246246

GCD(858, 861) = ( 858 x 861 ) / 246246

= 858 / 861

= 858

Step2:

LCM(3, 320) = 960

GCD(3, 320) = ( 3 x 320 ) / 960

= 3 / 320

= 3

Step3:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

So, Greatest Common Divisor of 858, 861, 320, 573 is 1
