Therefore, GCD of numbers 432, 318, 730, 561 is 1

Given Input Data is 432, 318, 730, 561

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

Prime Factorization of 432 is 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 318 is 2 x 3 x 53

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 561 is 3 x 11 x 17

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(432, 318) = 22896

GCD(432, 318) = ( 432 x 318 ) / 22896

GCD(432, 318) = 137376 / 22896

GCD(432, 318) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 730

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

LCM(6, 730) = 2190

GCD(6, 730) = ( 6 x 730 ) / 2190

GCD(6, 730) = 4380 / 2190

GCD(6, 730) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 561

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

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

GCD(2, 561) = 1122 / 1122

GCD(2, 561) = 1

GCD of 432, 318, 730, 561 is 1
