Given numbers are 120, 115, 576, 449

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 115 are 5 x 23

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 449 are 449

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

Given numbers are 120, 115, 576, 449

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

Apply this formula for all numbers.

Step1:

LCM(120, 115) = 2760

GCD(120, 115) = ( 120 x 115 ) / 2760

= 120 / 115

= 120

Step2:

LCM(5, 576) = 2880

GCD(5, 576) = ( 5 x 576 ) / 2880

= 5 / 576

= 5

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 120, 115, 576, 449 is 1
