Given numbers are 321, 855, 694, 408

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

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

Prime factors of 694 are 2 x 347

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 321, 855, 694, 408

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

Apply this formula for all numbers.

Step1:

LCM(321, 855) = 91485

GCD(321, 855) = ( 321 x 855 ) / 91485

= 321 / 855

= 321

Step2:

LCM(3, 694) = 2082

GCD(3, 694) = ( 3 x 694 ) / 2082

= 3 / 694

= 3

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 321, 855, 694, 408 is 1
