Finding GCD of 207, 495, 285, 380 using Prime Factorization

Given Input Data is 207, 495, 285, 380

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 495 is 3 x 3 x 5 x 11

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 380 is 2 x 2 x 5 x 19

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

Finding GCD of 207, 495, 285, 380 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(207, 495) = 11385

GCD(207, 495) = ( 207 x 495 ) / 11385

GCD(207, 495) = 102465 / 11385

GCD(207, 495) = 9


Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 285

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

LCM(9, 285) = 855

GCD(9, 285) = ( 9 x 285 ) / 855

GCD(9, 285) = 2565 / 855

GCD(9, 285) = 3


Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 380

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

LCM(3, 380) = 1140

GCD(3, 380) = ( 3 x 380 ) / 1140

GCD(3, 380) = 1140 / 1140

GCD(3, 380) = 1

GCD of 207, 495, 285, 380 is 1
