Therefore, GCD of numbers 740, 405, 960, 621 is 1

Given Input Data is 740, 405, 960, 621

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

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 960 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(740, 405) = 59940

GCD(740, 405) = ( 740 x 405 ) / 59940

GCD(740, 405) = 299700 / 59940

GCD(740, 405) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 960

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

LCM(5, 960) = 960

GCD(5, 960) = ( 5 x 960 ) / 960

GCD(5, 960) = 4800 / 960

GCD(5, 960) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 621

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

LCM(5, 621) = 3105

GCD(5, 621) = ( 5 x 621 ) / 3105

GCD(5, 621) = 3105 / 3105

GCD(5, 621) = 1

GCD of 740, 405, 960, 621 is 1
