Finding GCD of 81, 1, 17, 79 using Prime Factorization

Given Input Data is 81, 1, 17, 79

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 1 is

Prime Factorization of 17 is 17

Prime Factorization of 79 is 79

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

Finding GCD of 81, 1, 17, 79 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(81, 1) = 81

GCD(81, 1) = ( 81 x 1 ) / 81

GCD(81, 1) = 81 / 81

GCD(81, 1) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 17

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

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

GCD(1, 17) = 17 / 17

GCD(1, 17) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

GCD of 81, 1, 17, 79 is 1
