Given numbers are 663, 945, 503, 624

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 503 are 503

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 663, 945, 503, 624

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

Apply this formula for all numbers.

Step1:

LCM(663, 945) = 208845

GCD(663, 945) = ( 663 x 945 ) / 208845

= 663 / 945

= 663

Step2:

LCM(3, 503) = 1509

GCD(3, 503) = ( 3 x 503 ) / 1509

= 3 / 503

= 3

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 663, 945, 503, 624 is 1
