Therefore, GCD of numbers 216, 831, 66, 320 is 1

Given Input Data is 216, 831, 66, 320

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

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 831 is 3 x 277

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

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(216, 831) = 59832

GCD(216, 831) = ( 216 x 831 ) / 59832

GCD(216, 831) = 179496 / 59832

GCD(216, 831) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 66

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

LCM(3, 66) = 66

GCD(3, 66) = ( 3 x 66 ) / 66

GCD(3, 66) = 198 / 66

GCD(3, 66) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 320

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

LCM(3, 320) = 960

GCD(3, 320) = ( 3 x 320 ) / 960

GCD(3, 320) = 960 / 960

GCD(3, 320) = 1

GCD of 216, 831, 66, 320 is 1
