Given numbers are 321, 819, 228, 770

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 321, 819, 228, 770

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

Apply this formula for all numbers.

Step1:

LCM(321, 819) = 87633

GCD(321, 819) = ( 321 x 819 ) / 87633

= 321 / 819

= 321

Step2:

LCM(3, 228) = 228

GCD(3, 228) = ( 3 x 228 ) / 228

= 3 / 228

= 3

Step3:

LCM(3, 770) = 2310

GCD(3, 770) = ( 3 x 770 ) / 2310

= 3 / 770

= 3

So, Greatest Common Divisor of 321, 819, 228, 770 is 1
