Given numbers are 644, 504, 313, 672

The list of prime factors of all numbers are

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

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 313 are 313

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

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

Given numbers are 644, 504, 313, 672

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

Apply this formula for all numbers.

Step1:

LCM(644, 504) = 11592

GCD(644, 504) = ( 644 x 504 ) / 11592

= 644 / 504

= 644

Step2:

LCM(28, 313) = 8764

GCD(28, 313) = ( 28 x 313 ) / 8764

= 28 / 313

= 28

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 644, 504, 313, 672 is 1
