Given numbers are 646, 432, 663, 699

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 663 are 3 x 13 x 17

Prime factors of 699 are 3 x 233

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

Given numbers are 646, 432, 663, 699

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

Apply this formula for all numbers.

Step1:

LCM(646, 432) = 139536

GCD(646, 432) = ( 646 x 432 ) / 139536

= 646 / 432

= 646

Step2:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

Step3:

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

= 1 / 699

= 1

So, Greatest Common Divisor of 646, 432, 663, 699 is 1
