Given Input Data is 270, 620, 63, 330

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

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 330 is 2 x 3 x 5 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(270, 620) = 16740

GCD(270, 620) = ( 270 x 620 ) / 16740

GCD(270, 620) = 167400 / 16740

GCD(270, 620) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 63

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

LCM(10, 63) = 630

GCD(10, 63) = ( 10 x 63 ) / 630

GCD(10, 63) = 630 / 630

GCD(10, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 330

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

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

GCD(1, 330) = 330 / 330

GCD(1, 330) = 1

GCD of 270, 620, 63, 330 is 1
