Given numbers are 855, 687, 302, 800

The list of prime factors of all numbers are

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

Prime factors of 687 are 3 x 229

Prime factors of 302 are 2 x 151

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 855, 687, 302, 800

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

Apply this formula for all numbers.

Step1:

LCM(855, 687) = 195795

GCD(855, 687) = ( 855 x 687 ) / 195795

= 855 / 687

= 855

Step2:

LCM(3, 302) = 906

GCD(3, 302) = ( 3 x 302 ) / 906

= 3 / 302

= 3

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 855, 687, 302, 800 is 1
