Therefore, GCD of numbers 821, 285, 410 is 1

Given Input Data is 821, 285, 410

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

Prime Factorization of 821 is 821

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 410 is 2 x 5 x 41

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(821, 285) = 233985

GCD(821, 285) = ( 821 x 285 ) / 233985

GCD(821, 285) = 233985 / 233985

GCD(821, 285) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 410

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

LCM(1, 410) = 410

GCD(1, 410) = ( 1 x 410 ) / 410

GCD(1, 410) = 410 / 410

GCD(1, 410) = 1

GCD of 821, 285, 410 is 1
