Given Input Data is 172, 450, 44, 419

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 419 is 419

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(172, 450) = 38700

GCD(172, 450) = ( 172 x 450 ) / 38700

GCD(172, 450) = 77400 / 38700

GCD(172, 450) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 44

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

LCM(2, 44) = 44

GCD(2, 44) = ( 2 x 44 ) / 44

GCD(2, 44) = 88 / 44

GCD(2, 44) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 419

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

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

GCD(2, 419) = 838 / 838

GCD(2, 419) = 1

GCD of 172, 450, 44, 419 is 1
