Therefore, GCD of numbers 840, 957, 720, 352 is 1

Given Input Data is 840, 957, 720, 352

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 352 is 2 x 2 x 2 x 2 x 2 x 11

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(840, 957) = 267960

GCD(840, 957) = ( 840 x 957 ) / 267960

GCD(840, 957) = 803880 / 267960

GCD(840, 957) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 720

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

LCM(3, 720) = 720

GCD(3, 720) = ( 3 x 720 ) / 720

GCD(3, 720) = 2160 / 720

GCD(3, 720) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 352

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

LCM(3, 352) = 1056

GCD(3, 352) = ( 3 x 352 ) / 1056

GCD(3, 352) = 1056 / 1056

GCD(3, 352) = 1

GCD of 840, 957, 720, 352 is 1
