Therefore, GCD of numbers 20, 835, 608, 862 is 1

Given Input Data is 20, 835, 608, 862

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 835 is 5 x 167

Prime Factorization of 608 is 2 x 2 x 2 x 2 x 2 x 19

Prime Factorization of 862 is 2 x 431

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(20, 835) = 3340

GCD(20, 835) = ( 20 x 835 ) / 3340

GCD(20, 835) = 16700 / 3340

GCD(20, 835) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 608

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

LCM(5, 608) = 3040

GCD(5, 608) = ( 5 x 608 ) / 3040

GCD(5, 608) = 3040 / 3040

GCD(5, 608) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 862

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

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

GCD(1, 862) = 862 / 862

GCD(1, 862) = 1

GCD of 20, 835, 608, 862 is 1
