Therefore, GCD of numbers 923, 845, 980 is 1

Given Input Data is 923, 845, 980

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

Prime Factorization of 923 is 13 x 71

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

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(923, 845) = 59995

GCD(923, 845) = ( 923 x 845 ) / 59995

GCD(923, 845) = 779935 / 59995

GCD(923, 845) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 980

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

LCM(13, 980) = 12740

GCD(13, 980) = ( 13 x 980 ) / 12740

GCD(13, 980) = 12740 / 12740

GCD(13, 980) = 1

GCD of 923, 845, 980 is 1
