Given Input Data is 256, 224, 68, 202

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

Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 224 is 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 202 is 2 x 101

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(256, 224) = 1792

GCD(256, 224) = ( 256 x 224 ) / 1792

GCD(256, 224) = 57344 / 1792

GCD(256, 224) = 32

Step2:

Here we consider the GCD from the above i.e. 32 as first number and the next as 68

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

LCM(32, 68) = 544

GCD(32, 68) = ( 32 x 68 ) / 544

GCD(32, 68) = 2176 / 544

GCD(32, 68) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 202

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

LCM(4, 202) = 404

GCD(4, 202) = ( 4 x 202 ) / 404

GCD(4, 202) = 808 / 404

GCD(4, 202) = 2

GCD of 256, 224, 68, 202 is 2
