Given numbers are 858, 327, 21, 854

The list of prime factors of all numbers are

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

Prime factors of 327 are 3 x 109

Prime factors of 21 are 3 x 7

Prime factors of 854 are 2 x 7 x 61

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

Given numbers are 858, 327, 21, 854

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

Apply this formula for all numbers.

Step1:

LCM(858, 327) = 93522

GCD(858, 327) = ( 858 x 327 ) / 93522

= 858 / 327

= 858

Step2:

LCM(3, 21) = 21

GCD(3, 21) = ( 3 x 21 ) / 21

= 3 / 21

= 3

Step3:

LCM(3, 854) = 2562

GCD(3, 854) = ( 3 x 854 ) / 2562

= 3 / 854

= 3

So, Greatest Common Divisor of 858, 327, 21, 854 is 1
