Given numbers are 420, 432, 369, 439

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Prime factors of 369 are 3 x 3 x 41

Prime factors of 439 are 439

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

Given numbers are 420, 432, 369, 439

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

Apply this formula for all numbers.

Step1:

LCM(420, 432) = 15120

GCD(420, 432) = ( 420 x 432 ) / 15120

= 420 / 432

= 420

Step2:

LCM(12, 369) = 1476

GCD(12, 369) = ( 12 x 369 ) / 1476

= 12 / 369

= 12

Step3:

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

= 3 / 439

= 3

So, Greatest Common Divisor of 420, 432, 369, 439 is 1
