Therefore, GCD of numbers 285, 243, 445, 614 is 1

Given Input Data is 285, 243, 445, 614

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 445 is 5 x 89

Prime Factorization of 614 is 2 x 307

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(285, 243) = 23085

GCD(285, 243) = ( 285 x 243 ) / 23085

GCD(285, 243) = 69255 / 23085

GCD(285, 243) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 445

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

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

GCD(3, 445) = 1335 / 1335

GCD(3, 445) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 614

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

LCM(1, 614) = 614

GCD(1, 614) = ( 1 x 614 ) / 614

GCD(1, 614) = 614 / 614

GCD(1, 614) = 1

GCD of 285, 243, 445, 614 is 1
