Given numbers are 321, 816, 993, 812

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 993 are 3 x 331

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 321, 816, 993, 812

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

Apply this formula for all numbers.

Step1:

LCM(321, 816) = 87312

GCD(321, 816) = ( 321 x 816 ) / 87312

= 321 / 816

= 321

Step2:

LCM(3, 993) = 993

GCD(3, 993) = ( 3 x 993 ) / 993

= 3 / 993

= 3

Step3:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 321, 816, 993, 812 is 1
