Given numbers are 672, 865, 621, 311

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 865 are 5 x 173

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 311 are 311

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

Given numbers are 672, 865, 621, 311

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

Apply this formula for all numbers.

Step1:

LCM(672, 865) = 581280

GCD(672, 865) = ( 672 x 865 ) / 581280

= 672 / 865

= 672

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 672, 865, 621, 311 is 1
