Given numbers are 318, 198, 790, 645

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 790 are 2 x 5 x 79

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 318, 198, 790, 645

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

Apply this formula for all numbers.

Step1:

LCM(318, 198) = 10494

GCD(318, 198) = ( 318 x 198 ) / 10494

= 318 / 198

= 318

Step2:

LCM(6, 790) = 2370

GCD(6, 790) = ( 6 x 790 ) / 2370

= 6 / 790

= 6

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 318, 198, 790, 645 is 1
