Given numbers are 663, 686, 725, 693

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 725 are 5 x 5 x 29

Prime factors of 693 are 3 x 3 x 7 x 11

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

Given numbers are 663, 686, 725, 693

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

Apply this formula for all numbers.

Step1:

LCM(663, 686) = 454818

GCD(663, 686) = ( 663 x 686 ) / 454818

= 663 / 686

= 663

Step2:

LCM(1, 725) = 725

GCD(1, 725) = ( 1 x 725 ) / 725

= 1 / 725

= 1

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 663, 686, 725, 693 is 1
