Given numbers are 320, 986, 387, 489

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 986 are 2 x 17 x 29

Prime factors of 387 are 3 x 3 x 43

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 320, 986, 387, 489

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

Apply this formula for all numbers.

Step1:

LCM(320, 986) = 157760

GCD(320, 986) = ( 320 x 986 ) / 157760

= 320 / 986

= 320

Step2:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

Step3:

LCM(1, 489) = 489

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

= 1 / 489

= 1

So, Greatest Common Divisor of 320, 986, 387, 489 is 1
