Given Input Data is 438, 606, 207, 875

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

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 875 is 5 x 5 x 5 x 7

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(438, 606) = 44238

GCD(438, 606) = ( 438 x 606 ) / 44238

GCD(438, 606) = 265428 / 44238

GCD(438, 606) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 207

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

LCM(6, 207) = 414

GCD(6, 207) = ( 6 x 207 ) / 414

GCD(6, 207) = 1242 / 414

GCD(6, 207) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 875

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

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

GCD(3, 875) = 2625 / 2625

GCD(3, 875) = 1

GCD of 438, 606, 207, 875 is 1
