Given numbers are 306, 774, 420, 289

The list of prime factors of all numbers are

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

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 289 are 17 x 17

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

Given numbers are 306, 774, 420, 289

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

Apply this formula for all numbers.

Step1:

LCM(306, 774) = 13158

GCD(306, 774) = ( 306 x 774 ) / 13158

= 306 / 774

= 306

Step2:

LCM(18, 420) = 1260

GCD(18, 420) = ( 18 x 420 ) / 1260

= 18 / 420

= 18

Step3:

LCM(6, 289) = 1734

GCD(6, 289) = ( 6 x 289 ) / 1734

= 6 / 289

= 6

So, Greatest Common Divisor of 306, 774, 420, 289 is 1
