Given numbers are 489, 553, 406, 404

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 553 are 7 x 79

Prime factors of 406 are 2 x 7 x 29

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 489, 553, 406, 404

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

Apply this formula for all numbers.

Step1:

LCM(489, 553) = 270417

GCD(489, 553) = ( 489 x 553 ) / 270417

= 489 / 553

= 489

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 489, 553, 406, 404 is 1
