Given Input Data is 989, 171, 45, 833

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

Prime Factorization of 989 is 23 x 43

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 833 is 7 x 7 x 17

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(989, 171) = 169119

GCD(989, 171) = ( 989 x 171 ) / 169119

GCD(989, 171) = 169119 / 169119

GCD(989, 171) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 45

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

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

GCD(1, 45) = 45 / 45

GCD(1, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 833

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

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

GCD(1, 833) = 833 / 833

GCD(1, 833) = 1

GCD of 989, 171, 45, 833 is 1
