Given numbers are 663, 390, 805, 339

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 805 are 5 x 7 x 23

Prime factors of 339 are 3 x 113

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

Given numbers are 663, 390, 805, 339

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

Apply this formula for all numbers.

Step1:

LCM(663, 390) = 6630

GCD(663, 390) = ( 663 x 390 ) / 6630

= 663 / 390

= 663

Step2:

LCM(39, 805) = 31395

GCD(39, 805) = ( 39 x 805 ) / 31395

= 39 / 805

= 39

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 663, 390, 805, 339 is 1
