Given Input Data is 808, 202, 26, 668

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

Prime Factorization of 808 is 2 x 2 x 2 x 101

Prime Factorization of 202 is 2 x 101

Prime Factorization of 26 is 2 x 13

Prime Factorization of 668 is 2 x 2 x 167

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(808, 202) = 808

GCD(808, 202) = ( 808 x 202 ) / 808

GCD(808, 202) = 163216 / 808

GCD(808, 202) = 202

Step2:

Here we consider the GCD from the above i.e. 202 as first number and the next as 26

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

LCM(202, 26) = 2626

GCD(202, 26) = ( 202 x 26 ) / 2626

GCD(202, 26) = 5252 / 2626

GCD(202, 26) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 668

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

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

GCD(2, 668) = 1336 / 668

GCD(2, 668) = 2

GCD of 808, 202, 26, 668 is 2
