Given numbers are 855, 165, 604, 822

The list of prime factors of all numbers are

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

Prime factors of 165 are 3 x 5 x 11

Prime factors of 604 are 2 x 2 x 151

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 855, 165, 604, 822

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

Apply this formula for all numbers.

Step1:

LCM(855, 165) = 9405

GCD(855, 165) = ( 855 x 165 ) / 9405

= 855 / 165

= 855

Step2:

LCM(15, 604) = 9060

GCD(15, 604) = ( 15 x 604 ) / 9060

= 15 / 604

= 15

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 855, 165, 604, 822 is 1
