Given Input Data is 436, 672, 835, 208

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

Prime Factorization of 436 is 2 x 2 x 109

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 835 is 5 x 167

Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13

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(436, 672) = 73248

GCD(436, 672) = ( 436 x 672 ) / 73248

GCD(436, 672) = 292992 / 73248

GCD(436, 672) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 835

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

LCM(4, 835) = 3340

GCD(4, 835) = ( 4 x 835 ) / 3340

GCD(4, 835) = 3340 / 3340

GCD(4, 835) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 208

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

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

GCD(1, 208) = 208 / 208

GCD(1, 208) = 1

GCD of 436, 672, 835, 208 is 1
