Greatest Common Divisior

We found the divisors of 10, 87, 47, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 87, 47, 89 is 1.

Therefore, GCD of numbers 10, 87, 47, 89 is 1

Given Input Data is 10, 87, 47, 89

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 87 is 3 x 29

Prime Factorization of 47 is 47

Prime Factorization of 89 is 89

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(10, 87) = 870

GCD(10, 87) = ( 10 x 87 ) / 870

GCD(10, 87) = 870 / 870

GCD(10, 87) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 47

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

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

GCD(1, 47) = 47 / 47

GCD(1, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

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

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 10, 87, 47, 89 is 1
