Given numbers are 355, 720, 910, 658

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 355, 720, 910, 658

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

Apply this formula for all numbers.

Step1:

LCM(355, 720) = 51120

GCD(355, 720) = ( 355 x 720 ) / 51120

= 355 / 720

= 355

Step2:

LCM(5, 910) = 910

GCD(5, 910) = ( 5 x 910 ) / 910

= 5 / 910

= 5

Step3:

LCM(5, 658) = 3290

GCD(5, 658) = ( 5 x 658 ) / 3290

= 5 / 658

= 5

So, Greatest Common Divisor of 355, 720, 910, 658 is 1
