Given numbers are 285, 519, 728, 406

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 519 are 3 x 173

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

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 285, 519, 728, 406

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

Apply this formula for all numbers.

Step1:

LCM(285, 519) = 49305

GCD(285, 519) = ( 285 x 519 ) / 49305

= 285 / 519

= 285

Step2:

LCM(3, 728) = 2184

GCD(3, 728) = ( 3 x 728 ) / 2184

= 3 / 728

= 3

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 285, 519, 728, 406 is 1
