Given Input Data is 168, 740, 447, 217

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

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 447 is 3 x 149

Prime Factorization of 217 is 7 x 31

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(168, 740) = 31080

GCD(168, 740) = ( 168 x 740 ) / 31080

GCD(168, 740) = 124320 / 31080

GCD(168, 740) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 447

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

LCM(4, 447) = 1788

GCD(4, 447) = ( 4 x 447 ) / 1788

GCD(4, 447) = 1788 / 1788

GCD(4, 447) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 217

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

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

GCD(1, 217) = 217 / 217

GCD(1, 217) = 1

GCD of 168, 740, 447, 217 is 1
