Finding GCD of 457, 458, 515, 789 using Prime Factorization

Given Input Data is 457, 458, 515, 789

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

Prime Factorization of 457 is 457

Prime Factorization of 458 is 2 x 229

Prime Factorization of 515 is 5 x 103

Prime Factorization of 789 is 3 x 263

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 457, 458, 515, 789 using LCM Formula

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(457, 458) = 209306

GCD(457, 458) = ( 457 x 458 ) / 209306

GCD(457, 458) = 209306 / 209306

GCD(457, 458) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 515

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

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

GCD(1, 515) = 515 / 515

GCD(1, 515) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 789

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

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

GCD(1, 789) = 789 / 789

GCD(1, 789) = 1

GCD of 457, 458, 515, 789 is 1
