Given numbers are 998, 321, 908, 720

The list of prime factors of all numbers are

Prime factors of 998 are 2 x 499

Prime factors of 321 are 3 x 107

Prime factors of 908 are 2 x 2 x 227

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

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

Given numbers are 998, 321, 908, 720

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

Apply this formula for all numbers.

Step1:

LCM(998, 321) = 320358

GCD(998, 321) = ( 998 x 321 ) / 320358

= 998 / 321

= 998

Step2:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 998, 321, 908, 720 is 1
