Therefore, GCD of numbers 606, 561, 455, 150 is 1

Given Input Data is 606, 561, 455, 150

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

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 150 is 2 x 3 x 5 x 5

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(606, 561) = 113322

GCD(606, 561) = ( 606 x 561 ) / 113322

GCD(606, 561) = 339966 / 113322

GCD(606, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 455

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

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

GCD(3, 455) = 1365 / 1365

GCD(3, 455) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 150

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

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

GCD(1, 150) = 150 / 150

GCD(1, 150) = 1

GCD of 606, 561, 455, 150 is 1
