Given numbers are 285, 282, 447, 289

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 282 are 2 x 3 x 47

Prime factors of 447 are 3 x 149

Prime factors of 289 are 17 x 17

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

Given numbers are 285, 282, 447, 289

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

Apply this formula for all numbers.

Step1:

LCM(285, 282) = 26790

GCD(285, 282) = ( 285 x 282 ) / 26790

= 285 / 282

= 285

Step2:

LCM(3, 447) = 447

GCD(3, 447) = ( 3 x 447 ) / 447

= 3 / 447

= 3

Step3:

LCM(3, 289) = 867

GCD(3, 289) = ( 3 x 289 ) / 867

= 3 / 289

= 3

So, Greatest Common Divisor of 285, 282, 447, 289 is 1
