The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 346 are 2 x 173

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 489, 346, 666, 990

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

Apply this formula for all numbers.

Step1:

LCM(489, 346) = 169194

GCD(489, 346) = ( 489 x 346 ) / 169194

= 489 / 346

= 489

Step2:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 489, 346, 666, 990 is 1
