Given numbers are 672, 620, 639, 328

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 620 are 2 x 2 x 5 x 31

Prime factors of 639 are 3 x 3 x 71

Prime factors of 328 are 2 x 2 x 2 x 41

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

Given numbers are 672, 620, 639, 328

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

Apply this formula for all numbers.

Step1:

LCM(672, 620) = 104160

GCD(672, 620) = ( 672 x 620 ) / 104160

= 672 / 620

= 672

Step2:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

Step3:

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

= 1 / 328

= 1

So, Greatest Common Divisor of 672, 620, 639, 328 is 1
