Given numbers are 717, 693, 208, 858

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

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

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

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

Given numbers are 717, 693, 208, 858

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

Apply this formula for all numbers.

Step1:

LCM(717, 693) = 165627

GCD(717, 693) = ( 717 x 693 ) / 165627

= 717 / 693

= 717

Step2:

LCM(3, 208) = 624

GCD(3, 208) = ( 3 x 208 ) / 624

= 3 / 208

= 3

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 717, 693, 208, 858 is 1
