Therefore, GCD of numbers 847, 638, 181, 886 is 1

Given Input Data is 847, 638, 181, 886

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

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 181 is 181

Prime Factorization of 886 is 2 x 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(847, 638) = 49126

GCD(847, 638) = ( 847 x 638 ) / 49126

GCD(847, 638) = 540386 / 49126

GCD(847, 638) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 181

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

LCM(11, 181) = 1991

GCD(11, 181) = ( 11 x 181 ) / 1991

GCD(11, 181) = 1991 / 1991

GCD(11, 181) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 886

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

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

GCD(1, 886) = 886 / 886

GCD(1, 886) = 1

GCD of 847, 638, 181, 886 is 1
