Given numbers are 855, 918, 420, 928

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

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

Given numbers are 855, 918, 420, 928

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

Apply this formula for all numbers.

Step1:

LCM(855, 918) = 87210

GCD(855, 918) = ( 855 x 918 ) / 87210

= 855 / 918

= 855

Step2:

LCM(9, 420) = 1260

GCD(9, 420) = ( 9 x 420 ) / 1260

= 9 / 420

= 9

Step3:

LCM(3, 928) = 2784

GCD(3, 928) = ( 3 x 928 ) / 2784

= 3 / 928

= 3

So, Greatest Common Divisor of 855, 918, 420, 928 is 1
