Given numbers are 306, 285, 381, 581

The list of prime factors of all numbers are

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

Prime factors of 285 are 3 x 5 x 19

Prime factors of 381 are 3 x 127

Prime factors of 581 are 7 x 83

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

Given numbers are 306, 285, 381, 581

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

Apply this formula for all numbers.

Step1:

LCM(306, 285) = 29070

GCD(306, 285) = ( 306 x 285 ) / 29070

= 306 / 285

= 306

Step2:

LCM(3, 381) = 381

GCD(3, 381) = ( 3 x 381 ) / 381

= 3 / 381

= 3

Step3:

LCM(3, 581) = 1743

GCD(3, 581) = ( 3 x 581 ) / 1743

= 3 / 581

= 3

So, Greatest Common Divisor of 306, 285, 381, 581 is 1
