Given numbers are 672, 310, 645, 439

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 310 are 2 x 5 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 439 are 439

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

Given numbers are 672, 310, 645, 439

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

Apply this formula for all numbers.

Step1:

LCM(672, 310) = 104160

GCD(672, 310) = ( 672 x 310 ) / 104160

= 672 / 310

= 672

Step2:

LCM(2, 645) = 1290

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

= 2 / 645

= 2

Step3:

LCM(1, 439) = 439

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

= 1 / 439

= 1

So, Greatest Common Divisor of 672, 310, 645, 439 is 1
