Given numbers are 717, 691, 872, 630

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 691 are 691

Prime factors of 872 are 2 x 2 x 2 x 109

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 717, 691, 872, 630

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

Apply this formula for all numbers.

Step1:

LCM(717, 691) = 495447

GCD(717, 691) = ( 717 x 691 ) / 495447

= 717 / 691

= 717

Step2:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 717, 691, 872, 630 is 1
