Finding GCD of 65, 3, 18, 55 using Prime Factorization

Given Input Data is 65, 3, 18, 55

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

Prime Factorization of 65 is 5 x 13

Prime Factorization of 3 is 3

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 55 is 5 x 11

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

Finding GCD of 65, 3, 18, 55 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(65, 3) = 195

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

GCD(65, 3) = 195 / 195

GCD(65, 3) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 18

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

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

GCD(1, 18) = 18 / 18

GCD(1, 18) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 55

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

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

GCD(1, 55) = 55 / 55

GCD(1, 55) = 1

GCD of 65, 3, 18, 55 is 1
