Therefore, GCD of numbers 330, 215, 68, 247 is 1

Given Input Data is 330, 215, 68, 247

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

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 247 is 13 x 19

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(330, 215) = 14190

GCD(330, 215) = ( 330 x 215 ) / 14190

GCD(330, 215) = 70950 / 14190

GCD(330, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 68

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

LCM(5, 68) = 340

GCD(5, 68) = ( 5 x 68 ) / 340

GCD(5, 68) = 340 / 340

GCD(5, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 247

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

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

GCD(1, 247) = 247 / 247

GCD(1, 247) = 1

GCD of 330, 215, 68, 247 is 1
