Given numbers are 449, 452, 646, 672

The list of prime factors of all numbers are

Prime factors of 449 are 449

Prime factors of 452 are 2 x 2 x 113

Prime factors of 646 are 2 x 17 x 19

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 449, 452, 646, 672

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

Apply this formula for all numbers.

Step1:

LCM(449, 452) = 202948

GCD(449, 452) = ( 449 x 452 ) / 202948

= 449 / 452

= 449

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 449, 452, 646, 672 is 1
