Given numbers are 398, 680, 798, 417

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 417 are 3 x 139

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

Given numbers are 398, 680, 798, 417

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

Apply this formula for all numbers.

Step1:

LCM(398, 680) = 135320

GCD(398, 680) = ( 398 x 680 ) / 135320

= 398 / 680

= 398

Step2:

LCM(2, 798) = 798

GCD(2, 798) = ( 2 x 798 ) / 798

= 2 / 798

= 2

Step3:

LCM(2, 417) = 834

GCD(2, 417) = ( 2 x 417 ) / 834

= 2 / 417

= 2

So, Greatest Common Divisor of 398, 680, 798, 417 is 1
