Given numbers are 663, 768, 409, 416

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 409 are 409

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 663, 768, 409, 416

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

Apply this formula for all numbers.

Step1:

LCM(663, 768) = 169728

GCD(663, 768) = ( 663 x 768 ) / 169728

= 663 / 768

= 663

Step2:

LCM(3, 409) = 1227

GCD(3, 409) = ( 3 x 409 ) / 1227

= 3 / 409

= 3

Step3:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 663, 768, 409, 416 is 1
