Given numbers are 805, 199, 798, 728

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 199 are 199

Prime factors of 798 are 2 x 3 x 7 x 19

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 805, 199, 798, 728

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

Apply this formula for all numbers.

Step1:

LCM(805, 199) = 160195

GCD(805, 199) = ( 805 x 199 ) / 160195

= 805 / 199

= 805

Step2:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

Step3:

LCM(1, 728) = 728

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

= 1 / 728

= 1

So, Greatest Common Divisor of 805, 199, 798, 728 is 1
