The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 398 are 2 x 199

Prime factors of 444 are 2 x 2 x 3 x 37

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 785, 398, 444, 728

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

Apply this formula for all numbers.

Step1:

LCM(785, 398) = 312430

GCD(785, 398) = ( 785 x 398 ) / 312430

= 785 / 398

= 785

Step2:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

Step3:

LCM(1, 728) = 728

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

= 1 / 728

= 1

So, Greatest Common Divisor of 785, 398, 444, 728 is 1
