Therefore, GCD of numbers 438, 435, 443 is 1

Given Input Data is 438, 435, 443

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

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 443 is 443

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(438, 435) = 63510

GCD(438, 435) = ( 438 x 435 ) / 63510

GCD(438, 435) = 190530 / 63510

GCD(438, 435) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 443

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

LCM(3, 443) = 1329

GCD(3, 443) = ( 3 x 443 ) / 1329

GCD(3, 443) = 1329 / 1329

GCD(3, 443) = 1

GCD of 438, 435, 443 is 1
