Therefore, GCD of numbers 210, 225, 153, 385 is 1

Given Input Data is 210, 225, 153, 385

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 385 is 5 x 7 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(210, 225) = 3150

GCD(210, 225) = ( 210 x 225 ) / 3150

GCD(210, 225) = 47250 / 3150

GCD(210, 225) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 153

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

LCM(15, 153) = 765

GCD(15, 153) = ( 15 x 153 ) / 765

GCD(15, 153) = 2295 / 765

GCD(15, 153) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 385

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

LCM(3, 385) = 1155

GCD(3, 385) = ( 3 x 385 ) / 1155

GCD(3, 385) = 1155 / 1155

GCD(3, 385) = 1

GCD of 210, 225, 153, 385 is 1
