Greatest Common Divisior

We found the divisors of 143, 148, 61, 404 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 143, 148, 61, 404 is 1.

Therefore, GCD of numbers 143, 148, 61, 404 is 1

Given Input Data is 143, 148, 61, 404

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

Prime Factorization of 143 is 11 x 13

Prime Factorization of 148 is 2 x 2 x 37

Prime Factorization of 61 is 61

Prime Factorization of 404 is 2 x 2 x 101

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(143, 148) = 21164

GCD(143, 148) = ( 143 x 148 ) / 21164

GCD(143, 148) = 21164 / 21164

GCD(143, 148) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 404

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

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

GCD(1, 404) = 404 / 404

GCD(1, 404) = 1

GCD of 143, 148, 61, 404 is 1
