Given Input Data is 550, 270, 989

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

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 989 is 23 x 43

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(550, 270) = 14850

GCD(550, 270) = ( 550 x 270 ) / 14850

GCD(550, 270) = 148500 / 14850

GCD(550, 270) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 989

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

LCM(10, 989) = 9890

GCD(10, 989) = ( 10 x 989 ) / 9890

GCD(10, 989) = 9890 / 9890

GCD(10, 989) = 1

GCD of 550, 270, 989 is 1
