Therefore, GCD of numbers 429, 247, 18, 295 is 1

Given Input Data is 429, 247, 18, 295

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

Prime Factorization of 429 is 3 x 11 x 13

Prime Factorization of 247 is 13 x 19

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 295 is 5 x 59

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(429, 247) = 8151

GCD(429, 247) = ( 429 x 247 ) / 8151

GCD(429, 247) = 105963 / 8151

GCD(429, 247) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 18

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

LCM(13, 18) = 234

GCD(13, 18) = ( 13 x 18 ) / 234

GCD(13, 18) = 234 / 234

GCD(13, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 295

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

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

GCD(1, 295) = 295 / 295

GCD(1, 295) = 1

GCD of 429, 247, 18, 295 is 1
