Given Input Data is 133, 945, 15, 847

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

Prime Factorization of 133 is 7 x 19

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 15 is 3 x 5

Prime Factorization of 847 is 7 x 11 x 11

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(133, 945) = 17955

GCD(133, 945) = ( 133 x 945 ) / 17955

GCD(133, 945) = 125685 / 17955

GCD(133, 945) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 15

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

LCM(7, 15) = 105

GCD(7, 15) = ( 7 x 15 ) / 105

GCD(7, 15) = 105 / 105

GCD(7, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 847

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

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

GCD(1, 847) = 847 / 847

GCD(1, 847) = 1

GCD of 133, 945, 15, 847 is 1
