Given numbers are 489, 140, 355, 306

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 355 are 5 x 71

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 489, 140, 355, 306

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

Apply this formula for all numbers.

Step1:

LCM(489, 140) = 68460

GCD(489, 140) = ( 489 x 140 ) / 68460

= 489 / 140

= 489

Step2:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 489, 140, 355, 306 is 1
