Therefore, GCD of numbers 423, 820, 92 is 1

Given Input Data is 423, 820, 92

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

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 92 is 2 x 2 x 23

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(423, 820) = 346860

GCD(423, 820) = ( 423 x 820 ) / 346860

GCD(423, 820) = 346860 / 346860

GCD(423, 820) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 92

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

LCM(1, 92) = 92

GCD(1, 92) = ( 1 x 92 ) / 92

GCD(1, 92) = 92 / 92

GCD(1, 92) = 1

GCD of 423, 820, 92 is 1
