The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Prime factors of 284 are 2 x 2 x 71

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

Given numbers are 621, 912, 858, 284

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

Apply this formula for all numbers.

Step1:

LCM(621, 912) = 188784

GCD(621, 912) = ( 621 x 912 ) / 188784

= 621 / 912

= 621

Step2:

LCM(3, 858) = 858

GCD(3, 858) = ( 3 x 858 ) / 858

= 3 / 858

= 3

Step3:

LCM(3, 284) = 852

GCD(3, 284) = ( 3 x 284 ) / 852

= 3 / 284

= 3

So, Greatest Common Divisor of 621, 912, 858, 284 is 1
