Greatest Common Divisior

We found the divisors of 720, 602, 61, 120 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 720, 602, 61, 120 is 1.

Therefore, GCD of numbers 720, 602, 61, 120 is 1

Given Input Data is 720, 602, 61, 120

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

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

Prime Factorization of 602 is 2 x 7 x 43

Prime Factorization of 61 is 61

Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5

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(720, 602) = 216720

GCD(720, 602) = ( 720 x 602 ) / 216720

GCD(720, 602) = 433440 / 216720

GCD(720, 602) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 61

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

LCM(2, 61) = 122

GCD(2, 61) = ( 2 x 61 ) / 122

GCD(2, 61) = 122 / 122

GCD(2, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 120

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

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

GCD(1, 120) = 120 / 120

GCD(1, 120) = 1

GCD of 720, 602, 61, 120 is 1
