Given numbers are 306, 412, 728, 815

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 412 are 2 x 2 x 103

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

Prime factors of 815 are 5 x 163

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

Given numbers are 306, 412, 728, 815

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

Apply this formula for all numbers.

Step1:

LCM(306, 412) = 63036

GCD(306, 412) = ( 306 x 412 ) / 63036

= 306 / 412

= 306

Step2:

LCM(2, 728) = 728

GCD(2, 728) = ( 2 x 728 ) / 728

= 2 / 728

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 306, 412, 728, 815 is 1
