Given numbers are 305, 828, 612, 605

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 605 are 5 x 11 x 11

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

Given numbers are 305, 828, 612, 605

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

Apply this formula for all numbers.

Step1:

LCM(305, 828) = 252540

GCD(305, 828) = ( 305 x 828 ) / 252540

= 305 / 828

= 305

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 305, 828, 612, 605 is 1
