Therefore, GCD of numbers 931, 133, 81, 989 is 1

Given Input Data is 931, 133, 81, 989

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

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 133 is 7 x 19

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(931, 133) = 931

GCD(931, 133) = ( 931 x 133 ) / 931

GCD(931, 133) = 123823 / 931

GCD(931, 133) = 133

Step2:

Here we consider the GCD from the above i.e. 133 as first number and the next as 81

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

LCM(133, 81) = 10773

GCD(133, 81) = ( 133 x 81 ) / 10773

GCD(133, 81) = 10773 / 10773

GCD(133, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 989

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

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

GCD(1, 989) = 989 / 989

GCD(1, 989) = 1

GCD of 931, 133, 81, 989 is 1
