Finding GCD of 660, 392, 455 using Prime Factorization

Given Input Data is 660, 392, 455

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 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 455 is 5 x 7 x 13

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

Finding GCD of 660, 392, 455 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, 392) = 64680

GCD(660, 392) = ( 660 x 392 ) / 64680

GCD(660, 392) = 258720 / 64680

GCD(660, 392) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 455

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

LCM(4, 455) = 1820

GCD(4, 455) = ( 4 x 455 ) / 1820

GCD(4, 455) = 1820 / 1820

GCD(4, 455) = 1

GCD of 660, 392, 455 is 1
