Given Input Data is 798, 885, 66, 890

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

Prime Factorization of 798 is 2 x 3 x 7 x 19

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 890 is 2 x 5 x 89

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(798, 885) = 235410

GCD(798, 885) = ( 798 x 885 ) / 235410

GCD(798, 885) = 706230 / 235410

GCD(798, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 66

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

LCM(3, 66) = 66

GCD(3, 66) = ( 3 x 66 ) / 66

GCD(3, 66) = 198 / 66

GCD(3, 66) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 890

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

LCM(3, 890) = 2670

GCD(3, 890) = ( 3 x 890 ) / 2670

GCD(3, 890) = 2670 / 2670

GCD(3, 890) = 1

GCD of 798, 885, 66, 890 is 1
