Therefore, GCD of numbers 12, 543, 730, 497 is 1

Given Input Data is 12, 543, 730, 497

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 543 is 3 x 181

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 497 is 7 x 71

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(12, 543) = 2172

GCD(12, 543) = ( 12 x 543 ) / 2172

GCD(12, 543) = 6516 / 2172

GCD(12, 543) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 730

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

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

GCD(3, 730) = 2190 / 2190

GCD(3, 730) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 497

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

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

GCD(1, 497) = 497 / 497

GCD(1, 497) = 1

GCD of 12, 543, 730, 497 is 1
