Given Input Data is 447, 783, 703, 280

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 703 is 19 x 37

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

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(447, 783) = 116667

GCD(447, 783) = ( 447 x 783 ) / 116667

GCD(447, 783) = 350001 / 116667

GCD(447, 783) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 703

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

LCM(3, 703) = 2109

GCD(3, 703) = ( 3 x 703 ) / 2109

GCD(3, 703) = 2109 / 2109

GCD(3, 703) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 280

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

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

GCD(1, 280) = 280 / 280

GCD(1, 280) = 1

GCD of 447, 783, 703, 280 is 1
