Given Input Data is 550, 985, 45, 439

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 985 is 5 x 197

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 439 is 439

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, 985) = 108350

GCD(550, 985) = ( 550 x 985 ) / 108350

GCD(550, 985) = 541750 / 108350

GCD(550, 985) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 45

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

LCM(5, 45) = 45

GCD(5, 45) = ( 5 x 45 ) / 45

GCD(5, 45) = 225 / 45

GCD(5, 45) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 439

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

LCM(5, 439) = 2195

GCD(5, 439) = ( 5 x 439 ) / 2195

GCD(5, 439) = 2195 / 2195

GCD(5, 439) = 1

GCD of 550, 985, 45, 439 is 1
