Given numbers are 398, 794, 800, 487

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 794 are 2 x 397

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 487 are 487

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

Given numbers are 398, 794, 800, 487

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

Apply this formula for all numbers.

Step1:

LCM(398, 794) = 158006

GCD(398, 794) = ( 398 x 794 ) / 158006

= 398 / 794

= 398

Step2:

LCM(2, 800) = 800

GCD(2, 800) = ( 2 x 800 ) / 800

= 2 / 800

= 2

Step3:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

So, Greatest Common Divisor of 398, 794, 800, 487 is 1
