Given Input Data is 552, 989, 50, 391

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

Prime Factorization of 552 is 2 x 2 x 2 x 3 x 23

Prime Factorization of 989 is 23 x 43

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 391 is 17 x 23

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(552, 989) = 23736

GCD(552, 989) = ( 552 x 989 ) / 23736

GCD(552, 989) = 545928 / 23736

GCD(552, 989) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 50

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

LCM(23, 50) = 1150

GCD(23, 50) = ( 23 x 50 ) / 1150

GCD(23, 50) = 1150 / 1150

GCD(23, 50) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 552, 989, 50, 391 is 1
