Given numbers are 398, 558, 217, 966

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 217 are 7 x 31

Prime factors of 966 are 2 x 3 x 7 x 23

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

Given numbers are 398, 558, 217, 966

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

Apply this formula for all numbers.

Step1:

LCM(398, 558) = 111042

GCD(398, 558) = ( 398 x 558 ) / 111042

= 398 / 558

= 398

Step2:

LCM(2, 217) = 434

GCD(2, 217) = ( 2 x 217 ) / 434

= 2 / 217

= 2

Step3:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

So, Greatest Common Divisor of 398, 558, 217, 966 is 1
