Given numbers are 449, 440, 728, 556

The list of prime factors of all numbers are

Prime factors of 449 are 449

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 449, 440, 728, 556

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

Apply this formula for all numbers.

Step1:

LCM(449, 440) = 197560

GCD(449, 440) = ( 449 x 440 ) / 197560

= 449 / 440

= 449

Step2:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 449, 440, 728, 556 is 1
