Therefore, GCD of numbers 815, 632, 158 is 1

Given Input Data is 815, 632, 158

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 632 is 2 x 2 x 2 x 79

Prime Factorization of 158 is 2 x 79

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(815, 632) = 515080

GCD(815, 632) = ( 815 x 632 ) / 515080

GCD(815, 632) = 515080 / 515080

GCD(815, 632) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 158

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

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

GCD(1, 158) = 158 / 158

GCD(1, 158) = 1

GCD of 815, 632, 158 is 1
