Finding GCD of 3, 30, 65 using Prime Factorization

Given Input Data is 3, 30, 65

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

Prime Factorization of 3 is 3

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 65 is 5 x 13

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

Finding GCD of 3, 30, 65 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(3, 30) = 30

GCD(3, 30) = ( 3 x 30 ) / 30

GCD(3, 30) = 90 / 30

GCD(3, 30) = 3


Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 65

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

LCM(3, 65) = 195

GCD(3, 65) = ( 3 x 65 ) / 195

GCD(3, 65) = 195 / 195

GCD(3, 65) = 1

GCD of 3, 30, 65 is 1
