The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 406 are 2 x 7 x 29

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 589 are 19 x 31

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

Given numbers are 978, 406, 396, 589

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

Apply this formula for all numbers.

Step1:

LCM(978, 406) = 198534

GCD(978, 406) = ( 978 x 406 ) / 198534

= 978 / 406

= 978

Step2:

LCM(2, 396) = 396

GCD(2, 396) = ( 2 x 396 ) / 396

= 2 / 396

= 2

Step3:

LCM(2, 589) = 1178

GCD(2, 589) = ( 2 x 589 ) / 1178

= 2 / 589

= 2

So, Greatest Common Divisor of 978, 406, 396, 589 is 1
