Greatest Common Divisior

We found the divisors of 131, 720, 68, 780 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 131, 720, 68, 780 is 1.

Therefore, GCD of numbers 131, 720, 68, 780 is 1

Given Input Data is 131, 720, 68, 780

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

Prime Factorization of 131 is 131

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

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 780 is 2 x 2 x 3 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(131, 720) = 94320

GCD(131, 720) = ( 131 x 720 ) / 94320

GCD(131, 720) = 94320 / 94320

GCD(131, 720) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 68

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

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

GCD(1, 68) = 68 / 68

GCD(1, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 780

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

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

GCD(1, 780) = 780 / 780

GCD(1, 780) = 1

GCD of 131, 720, 68, 780 is 1
