Given numbers are 815, 306, 307, 489

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 307 are 307

Prime factors of 489 are 3 x 163

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

Given numbers are 815, 306, 307, 489

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

Apply this formula for all numbers.

Step1:

LCM(815, 306) = 249390

GCD(815, 306) = ( 815 x 306 ) / 249390

= 815 / 306

= 815

Step2:

LCM(1, 307) = 307

GCD(1, 307) = ( 1 x 307 ) / 307

= 1 / 307

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 815, 306, 307, 489 is 1
