Finding GCD of 18, 25, 70 using Prime Factorization

Given Input Data is 18, 25, 70

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 25 is 5 x 5

Prime Factorization of 70 is 2 x 5 x 7

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

Finding GCD of 18, 25, 70 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(18, 25) = 450

GCD(18, 25) = ( 18 x 25 ) / 450

GCD(18, 25) = 450 / 450

GCD(18, 25) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

GCD of 18, 25, 70 is 1
