### Finding GCD of 645, 748, 966, 205 using Prime Factorization

Given Input Data is 645, 748, 966, 205

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 748 is 2 x 2 x 11 x 17

Prime Factorization of 966 is 2 x 3 x 7 x 23

Prime Factorization of 205 is 5 x 41

### Finding GCD of 645, 748, 966, 205 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(645, 748) = 482460

GCD(645, 748) = ( 645 x 748 ) / 482460

GCD(645, 748) = 482460 / 482460

GCD(645, 748) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 966

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

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

GCD(1, 966) = 966 / 966

GCD(1, 966) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 205

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

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

GCD(1, 205) = 205 / 205

GCD(1, 205) = 1

GCD of 645, 748, 966, 205 is 1
