Given numbers are 121, 341, 840, 289

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 341 are 11 x 31

Prime factors of 840 are 2 x 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 121, 341, 840, 289

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

Apply this formula for all numbers.

Step1:

LCM(121, 341) = 3751

GCD(121, 341) = ( 121 x 341 ) / 3751

= 121 / 341

= 121

Step2:

LCM(11, 840) = 9240

GCD(11, 840) = ( 11 x 840 ) / 9240

= 11 / 840

= 11

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 121, 341, 840, 289 is 1
