We found the divisors of 121, 484, 91, 195 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 121, 484, 91, 195 is 1.

Therefore, GCD of numbers 121, 484, 91, 195 is 1

Given Input Data is 121, 484, 91, 195

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 121 is 11 x 11

Prime Factorization of 484 is 2 x 2 x 11 x 11

Prime Factorization of 91 is 7 x 13

Prime Factorization of 195 is 3 x 5 x 13

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(121, 484) = 484

GCD(121, 484) = ( 121 x 484 ) / 484

GCD(121, 484) = 58564 / 484

GCD(121, 484) = 121

Step2:

Here we consider the GCD from the above i.e. 121 as first number and the next as 91

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

LCM(121, 91) = 11011

GCD(121, 91) = ( 121 x 91 ) / 11011

GCD(121, 91) = 11011 / 11011

GCD(121, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 195

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

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

GCD(1, 195) = 195 / 195

GCD(1, 195) = 1

GCD of 121, 484, 91, 195 is 1
