Given numbers are 198, 605, 561, 834

The list of prime factors of all numbers are

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 605 are 5 x 11 x 11

Prime factors of 561 are 3 x 11 x 17

Prime factors of 834 are 2 x 3 x 139

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

Given numbers are 198, 605, 561, 834

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

Apply this formula for all numbers.

Step1:

LCM(198, 605) = 10890

GCD(198, 605) = ( 198 x 605 ) / 10890

= 198 / 605

= 198

Step2:

LCM(11, 561) = 561

GCD(11, 561) = ( 11 x 561 ) / 561

= 11 / 561

= 11

Step3:

LCM(11, 834) = 9174

GCD(11, 834) = ( 11 x 834 ) / 9174

= 11 / 834

= 11

So, Greatest Common Divisor of 198, 605, 561, 834 is 1
