Given Input Data is 424, 316, 686, 246

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 316 is 2 x 2 x 79

Prime Factorization of 686 is 2 x 7 x 7 x 7

Prime Factorization of 246 is 2 x 3 x 41

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(424, 316) = 33496

GCD(424, 316) = ( 424 x 316 ) / 33496

GCD(424, 316) = 133984 / 33496

GCD(424, 316) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 686

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

LCM(4, 686) = 1372

GCD(4, 686) = ( 4 x 686 ) / 1372

GCD(4, 686) = 2744 / 1372

GCD(4, 686) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 246

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

LCM(2, 246) = 246

GCD(2, 246) = ( 2 x 246 ) / 246

GCD(2, 246) = 492 / 246

GCD(2, 246) = 2

GCD of 424, 316, 686, 246 is 2
