Given numbers are 423, 500, 672, 646

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 423, 500, 672, 646

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

Apply this formula for all numbers.

Step1:

LCM(423, 500) = 211500

GCD(423, 500) = ( 423 x 500 ) / 211500

= 423 / 500

= 423

Step2:

LCM(1, 672) = 672

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

= 1 / 672

= 1

Step3:

LCM(1, 646) = 646

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

= 1 / 646

= 1

So, Greatest Common Divisor of 423, 500, 672, 646 is 1
