Therefore, GCD of numbers 630, 702, 40, 879 is 1

Given Input Data is 630, 702, 40, 879

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 702 is 2 x 3 x 3 x 3 x 13

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 879 is 3 x 293

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(630, 702) = 24570

GCD(630, 702) = ( 630 x 702 ) / 24570

GCD(630, 702) = 442260 / 24570

GCD(630, 702) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 40

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

LCM(18, 40) = 360

GCD(18, 40) = ( 18 x 40 ) / 360

GCD(18, 40) = 720 / 360

GCD(18, 40) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 879

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

LCM(2, 879) = 1758

GCD(2, 879) = ( 2 x 879 ) / 1758

GCD(2, 879) = 1758 / 1758

GCD(2, 879) = 1

GCD of 630, 702, 40, 879 is 1
