Therefore, GCD of numbers 55, 230, 243, 190 is 1

Given Input Data is 55, 230, 243, 190

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 230 is 2 x 5 x 23

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 190 is 2 x 5 x 19

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(55, 230) = 2530

GCD(55, 230) = ( 55 x 230 ) / 2530

GCD(55, 230) = 12650 / 2530

GCD(55, 230) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 243

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

LCM(5, 243) = 1215

GCD(5, 243) = ( 5 x 243 ) / 1215

GCD(5, 243) = 1215 / 1215

GCD(5, 243) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 190

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

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

GCD(1, 190) = 190 / 190

GCD(1, 190) = 1

GCD of 55, 230, 243, 190 is 1
