Greatest Common Divisior

We found the divisors of 723, 661, 80, 130 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 723, 661, 80, 130 is 1.

Therefore, GCD of numbers 723, 661, 80, 130 is 1

Given Input Data is 723, 661, 80, 130

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

Prime Factorization of 723 is 3 x 241

Prime Factorization of 661 is 661

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 130 is 2 x 5 x 13

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(723, 661) = 477903

GCD(723, 661) = ( 723 x 661 ) / 477903

GCD(723, 661) = 477903 / 477903

GCD(723, 661) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 80

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

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

GCD(1, 80) = 80 / 80

GCD(1, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 130

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

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

GCD(1, 130) = 130 / 130

GCD(1, 130) = 1

GCD of 723, 661, 80, 130 is 1
