Given numbers are 289, 306, 855, 378

The list of prime factors of all numbers are

Prime factors of 289 are 17 x 17

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

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 289, 306, 855, 378

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

Apply this formula for all numbers.

Step1:

LCM(289, 306) = 5202

GCD(289, 306) = ( 289 x 306 ) / 5202

= 289 / 306

= 289

Step2:

LCM(17, 855) = 14535

GCD(17, 855) = ( 17 x 855 ) / 14535

= 17 / 855

= 17

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 289, 306, 855, 378 is 1
