Therefore, GCD of numbers 819, 871, 91, 609 is 1

Given Input Data is 819, 871, 91, 609

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 871 is 13 x 67

Prime Factorization of 91 is 7 x 13

Prime Factorization of 609 is 3 x 7 x 29

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(819, 871) = 54873

GCD(819, 871) = ( 819 x 871 ) / 54873

GCD(819, 871) = 713349 / 54873

GCD(819, 871) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 91

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

LCM(13, 91) = 91

GCD(13, 91) = ( 13 x 91 ) / 91

GCD(13, 91) = 1183 / 91

GCD(13, 91) = 13

Step3:

Here we consider the GCD from the above i.e. 13 as first number and the next as 609

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

LCM(13, 609) = 7917

GCD(13, 609) = ( 13 x 609 ) / 7917

GCD(13, 609) = 7917 / 7917

GCD(13, 609) = 1

GCD of 819, 871, 91, 609 is 1
