Given numbers are 406, 603, 257, 728

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 603 are 3 x 3 x 67

Prime factors of 257 are 257

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

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

Given numbers are 406, 603, 257, 728

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

Apply this formula for all numbers.

Step1:

LCM(406, 603) = 244818

GCD(406, 603) = ( 406 x 603 ) / 244818

= 406 / 603

= 406

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 728) = 728

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

= 1 / 728

= 1

So, Greatest Common Divisor of 406, 603, 257, 728 is 1
