Therefore, GCD of numbers 91, 130, 804, 991 is 1

Given Input Data is 91, 130, 804, 991

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 804 is 2 x 2 x 3 x 67

Prime Factorization of 991 is 991

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(91, 130) = 910

GCD(91, 130) = ( 91 x 130 ) / 910

GCD(91, 130) = 11830 / 910

GCD(91, 130) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 804

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

LCM(13, 804) = 10452

GCD(13, 804) = ( 13 x 804 ) / 10452

GCD(13, 804) = 10452 / 10452

GCD(13, 804) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 991

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

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

GCD(1, 991) = 991 / 991

GCD(1, 991) = 1

GCD of 91, 130, 804, 991 is 1
