Therefore, GCD of numbers 489, 242, 429 is 1

Given Input Data is 489, 242, 429

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

Prime Factorization of 489 is 3 x 163

Prime Factorization of 242 is 2 x 11 x 11

Prime Factorization of 429 is 3 x 11 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(489, 242) = 118338

GCD(489, 242) = ( 489 x 242 ) / 118338

GCD(489, 242) = 118338 / 118338

GCD(489, 242) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 429

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

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

GCD(1, 429) = 429 / 429

GCD(1, 429) = 1

GCD of 489, 242, 429 is 1
