Given numbers are 717, 858, 395, 690

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 395 are 5 x 79

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 717, 858, 395, 690

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

Apply this formula for all numbers.

Step1:

LCM(717, 858) = 205062

GCD(717, 858) = ( 717 x 858 ) / 205062

= 717 / 858

= 717

Step2:

LCM(3, 395) = 1185

GCD(3, 395) = ( 3 x 395 ) / 1185

= 3 / 395

= 3

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 717, 858, 395, 690 is 1
