Given numbers are 985, 405, 302, 855

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 302 are 2 x 151

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

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

Given numbers are 985, 405, 302, 855

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

Apply this formula for all numbers.

Step1:

LCM(985, 405) = 79785

GCD(985, 405) = ( 985 x 405 ) / 79785

= 985 / 405

= 985

Step2:

LCM(5, 302) = 1510

GCD(5, 302) = ( 5 x 302 ) / 1510

= 5 / 302

= 5

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 985, 405, 302, 855 is 1
