Given numbers are 432, 570, 861, 289

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 570 are 2 x 3 x 5 x 19

Prime factors of 861 are 3 x 7 x 41

Prime factors of 289 are 17 x 17

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

Given numbers are 432, 570, 861, 289

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

Apply this formula for all numbers.

Step1:

LCM(432, 570) = 41040

GCD(432, 570) = ( 432 x 570 ) / 41040

= 432 / 570

= 432

Step2:

LCM(6, 861) = 1722

GCD(6, 861) = ( 6 x 861 ) / 1722

= 6 / 861

= 6

Step3:

LCM(3, 289) = 867

GCD(3, 289) = ( 3 x 289 ) / 867

= 3 / 289

= 3

So, Greatest Common Divisor of 432, 570, 861, 289 is 1
