Finding GCD of 660, 399, 808 using Prime Factorization

Given Input Data is 660, 399, 808

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 808 is 2 x 2 x 2 x 101

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

Finding GCD of 660, 399, 808 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(660, 399) = 87780

GCD(660, 399) = ( 660 x 399 ) / 87780

GCD(660, 399) = 263340 / 87780

GCD(660, 399) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 808

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

LCM(3, 808) = 2424

GCD(3, 808) = ( 3 x 808 ) / 2424

GCD(3, 808) = 2424 / 2424

GCD(3, 808) = 1

GCD of 660, 399, 808 is 1
