Finding GCD of 19, 15, 57 using Prime Factorization

Given Input Data is 19, 15, 57

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

Prime Factorization of 19 is 19

Prime Factorization of 15 is 3 x 5

Prime Factorization of 57 is 3 x 19

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

Finding GCD of 19, 15, 57 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(19, 15) = 285

GCD(19, 15) = ( 19 x 15 ) / 285

GCD(19, 15) = 285 / 285

GCD(19, 15) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 1

GCD of 19, 15, 57 is 1
