Given numbers are 285, 815, 432, 386

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 815 are 5 x 163

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 386 are 2 x 193

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

Given numbers are 285, 815, 432, 386

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

Apply this formula for all numbers.

Step1:

LCM(285, 815) = 46455

GCD(285, 815) = ( 285 x 815 ) / 46455

= 285 / 815

= 285

Step2:

LCM(5, 432) = 2160

GCD(5, 432) = ( 5 x 432 ) / 2160

= 5 / 432

= 5

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 285, 815, 432, 386 is 1
