Given numbers are 490, 356, 386, 717

The list of prime factors of all numbers are

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

Prime factors of 356 are 2 x 2 x 89

Prime factors of 386 are 2 x 193

Prime factors of 717 are 3 x 239

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

Given numbers are 490, 356, 386, 717

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

Apply this formula for all numbers.

Step1:

LCM(490, 356) = 87220

GCD(490, 356) = ( 490 x 356 ) / 87220

= 490 / 356

= 490

Step2:

LCM(2, 386) = 386

GCD(2, 386) = ( 2 x 386 ) / 386

= 2 / 386

= 2

Step3:

LCM(2, 717) = 1434

GCD(2, 717) = ( 2 x 717 ) / 1434

= 2 / 717

= 2

So, Greatest Common Divisor of 490, 356, 386, 717 is 1
