Greatest Common Divisior

We found the divisors of 930, 991, 40, 931 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 930, 991, 40, 931 is 1.

Therefore, GCD of numbers 930, 991, 40, 931 is 1

Given Input Data is 930, 991, 40, 931

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

Prime Factorization of 930 is 2 x 3 x 5 x 31

Prime Factorization of 991 is 991

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 931 is 7 x 7 x 19

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(930, 991) = 921630

GCD(930, 991) = ( 930 x 991 ) / 921630

GCD(930, 991) = 921630 / 921630

GCD(930, 991) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 930, 991, 40, 931 is 1
