Given numbers are 305, 705, 389, 310

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 705 are 3 x 5 x 47

Prime factors of 389 are 389

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 305, 705, 389, 310

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

Apply this formula for all numbers.

Step1:

LCM(305, 705) = 43005

GCD(305, 705) = ( 305 x 705 ) / 43005

= 305 / 705

= 305

Step2:

LCM(5, 389) = 1945

GCD(5, 389) = ( 5 x 389 ) / 1945

= 5 / 389

= 5

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 305, 705, 389, 310 is 1
