Given Input Data is 181, 414, 209, 945

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

Prime Factorization of 181 is 181

Prime Factorization of 414 is 2 x 3 x 3 x 23

Prime Factorization of 209 is 11 x 19

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

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(181, 414) = 74934

GCD(181, 414) = ( 181 x 414 ) / 74934

GCD(181, 414) = 74934 / 74934

GCD(181, 414) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 209

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

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

GCD(1, 209) = 209 / 209

GCD(1, 209) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 945

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

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

GCD(1, 945) = 945 / 945

GCD(1, 945) = 1

GCD of 181, 414, 209, 945 is 1
