Finding GCD of 34, 30, 80, 57 using Prime Factorization

Given Input Data is 34, 30, 80, 57

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

Prime Factorization of 34 is 2 x 17

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 80 is 2 x 2 x 2 x 2 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 34, 30, 80, 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(34, 30) = 510

GCD(34, 30) = ( 34 x 30 ) / 510

GCD(34, 30) = 1020 / 510

GCD(34, 30) = 2


Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 80

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

LCM(2, 80) = 80

GCD(2, 80) = ( 2 x 80 ) / 80

GCD(2, 80) = 160 / 80

GCD(2, 80) = 2


Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 57

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

LCM(2, 57) = 114

GCD(2, 57) = ( 2 x 57 ) / 114

GCD(2, 57) = 114 / 114

GCD(2, 57) = 1

GCD of 34, 30, 80, 57 is 1
