Therefore, GCD of numbers 490, 301, 21, 741 is 1

Given Input Data is 490, 301, 21, 741

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

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 301 is 7 x 43

Prime Factorization of 21 is 3 x 7

Prime Factorization of 741 is 3 x 13 x 19

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(490, 301) = 21070

GCD(490, 301) = ( 490 x 301 ) / 21070

GCD(490, 301) = 147490 / 21070

GCD(490, 301) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 21

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

LCM(7, 21) = 21

GCD(7, 21) = ( 7 x 21 ) / 21

GCD(7, 21) = 147 / 21

GCD(7, 21) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 741

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

LCM(7, 741) = 5187

GCD(7, 741) = ( 7 x 741 ) / 5187

GCD(7, 741) = 5187 / 5187

GCD(7, 741) = 1

GCD of 490, 301, 21, 741 is 1
