Therefore, GCD of numbers 121, 954, 221 is 1

Given Input Data is 121, 954, 221

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

Prime Factorization of 121 is 11 x 11

Prime Factorization of 954 is 2 x 3 x 3 x 53

Prime Factorization of 221 is 13 x 17

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, 954) = 115434

GCD(121, 954) = ( 121 x 954 ) / 115434

GCD(121, 954) = 115434 / 115434

GCD(121, 954) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 221

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

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

GCD(1, 221) = 221 / 221

GCD(1, 221) = 1

GCD of 121, 954, 221 is 1
