Therefore, GCD of numbers 861, 933, 84, 989 is 1

Given Input Data is 861, 933, 84, 989

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 933 is 3 x 311

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 989 is 23 x 43

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(861, 933) = 267771

GCD(861, 933) = ( 861 x 933 ) / 267771

GCD(861, 933) = 803313 / 267771

GCD(861, 933) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 84

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

LCM(3, 84) = 84

GCD(3, 84) = ( 3 x 84 ) / 84

GCD(3, 84) = 252 / 84

GCD(3, 84) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 989

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

LCM(3, 989) = 2967

GCD(3, 989) = ( 3 x 989 ) / 2967

GCD(3, 989) = 2967 / 2967

GCD(3, 989) = 1

GCD of 861, 933, 84, 989 is 1
