Therefore, GCD of numbers 840, 510, 631, 943 is 1

Given Input Data is 840, 510, 631, 943

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 510 is 2 x 3 x 5 x 17

Prime Factorization of 631 is 631

Prime Factorization of 943 is 23 x 41

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, 510) = 14280

GCD(840, 510) = ( 840 x 510 ) / 14280

GCD(840, 510) = 428400 / 14280

GCD(840, 510) = 30

Step2:

Here we consider the GCD from the above i.e. 30 as first number and the next as 631

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

LCM(30, 631) = 18930

GCD(30, 631) = ( 30 x 631 ) / 18930

GCD(30, 631) = 18930 / 18930

GCD(30, 631) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 943

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

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

GCD(1, 943) = 943 / 943

GCD(1, 943) = 1

GCD of 840, 510, 631, 943 is 1
