Therefore, GCD of numbers 445, 720, 19, 246 is 1

Given Input Data is 445, 720, 19, 246

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 19 is 19

Prime Factorization of 246 is 2 x 3 x 41

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(445, 720) = 64080

GCD(445, 720) = ( 445 x 720 ) / 64080

GCD(445, 720) = 320400 / 64080

GCD(445, 720) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 19

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

LCM(5, 19) = 95

GCD(5, 19) = ( 5 x 19 ) / 95

GCD(5, 19) = 95 / 95

GCD(5, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 246

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

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

GCD(1, 246) = 246 / 246

GCD(1, 246) = 1

GCD of 445, 720, 19, 246 is 1
