Given numbers are 311, 474, 672, 644

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 474 are 2 x 3 x 79

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

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 311, 474, 672, 644

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

Apply this formula for all numbers.

Step1:

LCM(311, 474) = 147414

GCD(311, 474) = ( 311 x 474 ) / 147414

= 311 / 474

= 311

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 311, 474, 672, 644 is 1
