Given numbers are 432, 939, 390, 115

The list of prime factors of all numbers are

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

Prime factors of 939 are 3 x 313

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 115 are 5 x 23

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

Given numbers are 432, 939, 390, 115

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

Apply this formula for all numbers.

Step1:

LCM(432, 939) = 135216

GCD(432, 939) = ( 432 x 939 ) / 135216

= 432 / 939

= 432

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 115) = 345

GCD(3, 115) = ( 3 x 115 ) / 345

= 3 / 115

= 3

So, Greatest Common Divisor of 432, 939, 390, 115 is 1
