Given numbers are 663, 679, 720, 579

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 679 are 7 x 97

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 579 are 3 x 193

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

Given numbers are 663, 679, 720, 579

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

Apply this formula for all numbers.

Step1:

LCM(663, 679) = 450177

GCD(663, 679) = ( 663 x 679 ) / 450177

= 663 / 679

= 663

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 663, 679, 720, 579 is 1
