Given numbers are 645, 812, 330, 439

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

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

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 439 are 439

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

Given numbers are 645, 812, 330, 439

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

Apply this formula for all numbers.

Step1:

LCM(645, 812) = 523740

GCD(645, 812) = ( 645 x 812 ) / 523740

= 645 / 812

= 645

Step2:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 645, 812, 330, 439 is 1
