Therefore, GCD of numbers 181, 821, 42, 800 is 1

Given Input Data is 181, 821, 42, 800

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

Prime Factorization of 181 is 181

Prime Factorization of 821 is 821

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 800 is 2 x 2 x 2 x 2 x 2 x 5 x 5

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(181, 821) = 148601

GCD(181, 821) = ( 181 x 821 ) / 148601

GCD(181, 821) = 148601 / 148601

GCD(181, 821) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 800

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

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

GCD(1, 800) = 800 / 800

GCD(1, 800) = 1

GCD of 181, 821, 42, 800 is 1
