Given numbers are 286, 170, 768, 261

The list of prime factors of all numbers are

Prime factors of 286 are 2 x 11 x 13

Prime factors of 170 are 2 x 5 x 17

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 286, 170, 768, 261

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

Apply this formula for all numbers.

Step1:

LCM(286, 170) = 24310

GCD(286, 170) = ( 286 x 170 ) / 24310

= 286 / 170

= 286

Step2:

LCM(2, 768) = 768

GCD(2, 768) = ( 2 x 768 ) / 768

= 2 / 768

= 2

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 286, 170, 768, 261 is 1
