Finding GCD of 55, 15, 36, 19 using Prime Factorization

Given Input Data is 55, 15, 36, 19

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 15 is 3 x 5

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 19 is 19

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

Finding GCD of 55, 15, 36, 19 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(55, 15) = 165

GCD(55, 15) = ( 55 x 15 ) / 165

GCD(55, 15) = 825 / 165

GCD(55, 15) = 5


Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 36

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

LCM(5, 36) = 180

GCD(5, 36) = ( 5 x 36 ) / 180

GCD(5, 36) = 180 / 180

GCD(5, 36) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

GCD of 55, 15, 36, 19 is 1
