The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 717, 490, 920, 870

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

Apply this formula for all numbers.

Step1:

LCM(717, 490) = 351330

GCD(717, 490) = ( 717 x 490 ) / 351330

= 717 / 490

= 717

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 717, 490, 920, 870 is 1
