Given Input Data is 965, 330, 18, 520

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

Prime Factorization of 965 is 5 x 193

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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(965, 330) = 63690

GCD(965, 330) = ( 965 x 330 ) / 63690

GCD(965, 330) = 318450 / 63690

GCD(965, 330) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 18

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

LCM(5, 18) = 90

GCD(5, 18) = ( 5 x 18 ) / 90

GCD(5, 18) = 90 / 90

GCD(5, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 520

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

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

GCD(1, 520) = 520 / 520

GCD(1, 520) = 1

GCD of 965, 330, 18, 520 is 1
