Given numbers are 986, 440, 810, 289

The list of prime factors of all numbers are

Prime factors of 986 are 2 x 17 x 29

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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 986, 440, 810, 289

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

Apply this formula for all numbers.

Step1:

LCM(986, 440) = 216920

GCD(986, 440) = ( 986 x 440 ) / 216920

= 986 / 440

= 986

Step2:

LCM(2, 810) = 810

GCD(2, 810) = ( 2 x 810 ) / 810

= 2 / 810

= 2

Step3:

LCM(2, 289) = 578

GCD(2, 289) = ( 2 x 289 ) / 578

= 2 / 289

= 2

So, Greatest Common Divisor of 986, 440, 810, 289 is 1
