Given numbers are 645, 364, 367, 321

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 367 are 367

Prime factors of 321 are 3 x 107

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

Given numbers are 645, 364, 367, 321

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

Apply this formula for all numbers.

Step1:

LCM(645, 364) = 234780

GCD(645, 364) = ( 645 x 364 ) / 234780

= 645 / 364

= 645

Step2:

LCM(1, 367) = 367

GCD(1, 367) = ( 1 x 367 ) / 367

= 1 / 367

= 1

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 645, 364, 367, 321 is 1
