The list of prime factors of all numbers are

Prime factors of 998 are 2 x 499

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 418 are 2 x 11 x 19

Prime factors of 647 are 647

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

Given numbers are 998, 320, 418, 647

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

Apply this formula for all numbers.

Step1:

LCM(998, 320) = 159680

GCD(998, 320) = ( 998 x 320 ) / 159680

= 998 / 320

= 998

Step2:

LCM(2, 418) = 418

GCD(2, 418) = ( 2 x 418 ) / 418

= 2 / 418

= 2

Step3:

LCM(2, 647) = 1294

GCD(2, 647) = ( 2 x 647 ) / 1294

= 2 / 647

= 2

So, Greatest Common Divisor of 998, 320, 418, 647 is 1
