Given numbers are 432, 385, 239, 643

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 385 are 5 x 7 x 11

Prime factors of 239 are 239

Prime factors of 643 are 643

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

Given numbers are 432, 385, 239, 643

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

Apply this formula for all numbers.

Step1:

LCM(432, 385) = 166320

GCD(432, 385) = ( 432 x 385 ) / 166320

= 432 / 385

= 432

Step2:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 432, 385, 239, 643 is 1
