Therefore, GCD of numbers 87, 891, 304, 913 is 1

Given Input Data is 87, 891, 304, 913

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

Prime Factorization of 913 is 11 x 83

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(87, 891) = 25839

GCD(87, 891) = ( 87 x 891 ) / 25839

GCD(87, 891) = 77517 / 25839

GCD(87, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 304

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

LCM(3, 304) = 912

GCD(3, 304) = ( 3 x 304 ) / 912

GCD(3, 304) = 912 / 912

GCD(3, 304) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 913

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

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

GCD(1, 913) = 913 / 913

GCD(1, 913) = 1

GCD of 87, 891, 304, 913 is 1
