Given Input Data is 450, 585, 857, 217

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

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

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 857 is 857

Prime Factorization of 217 is 7 x 31

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(450, 585) = 5850

GCD(450, 585) = ( 450 x 585 ) / 5850

GCD(450, 585) = 263250 / 5850

GCD(450, 585) = 45

Step2:

Here we consider the GCD from the above i.e. 45 as first number and the next as 857

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

LCM(45, 857) = 38565

GCD(45, 857) = ( 45 x 857 ) / 38565

GCD(45, 857) = 38565 / 38565

GCD(45, 857) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 217

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

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

GCD(1, 217) = 217 / 217

GCD(1, 217) = 1

GCD of 450, 585, 857, 217 is 1
