Finding GCD of 70, 80, 66 using Prime Factorization

Given Input Data is 70, 80, 66

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 66 is 2 x 3 x 11

Finding GCD of 70, 80, 66 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(70, 80) = 560

GCD(70, 80) = ( 70 x 80 ) / 560

GCD(70, 80) = 5600 / 560

GCD(70, 80) = 10


Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 66

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

LCM(10, 66) = 330

GCD(10, 66) = ( 10 x 66 ) / 330

GCD(10, 66) = 660 / 330

GCD(10, 66) = 2

GCD of 70, 80, 66 is 2
