Therefore, GCD of numbers 891, 540, 417, 448 is 1

Given Input Data is 891, 540, 417, 448

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

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Prime Factorization of 417 is 3 x 139

Prime Factorization of 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7

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

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(891, 540) = 17820

GCD(891, 540) = ( 891 x 540 ) / 17820

GCD(891, 540) = 481140 / 17820

GCD(891, 540) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 417

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

LCM(27, 417) = 3753

GCD(27, 417) = ( 27 x 417 ) / 3753

GCD(27, 417) = 11259 / 3753

GCD(27, 417) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 448

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

LCM(3, 448) = 1344

GCD(3, 448) = ( 3 x 448 ) / 1344

GCD(3, 448) = 1344 / 1344

GCD(3, 448) = 1

GCD of 891, 540, 417, 448 is 1
