We found the divisors of 130, 397, 40, 202 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 130, 397, 40, 202 is 1.

Therefore, GCD of numbers 130, 397, 40, 202 is 1

Given Input Data is 130, 397, 40, 202

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

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 397 is 397

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 202 is 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(130, 397) = 51610

GCD(130, 397) = ( 130 x 397 ) / 51610

GCD(130, 397) = 51610 / 51610

GCD(130, 397) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 202

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

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

GCD(1, 202) = 202 / 202

GCD(1, 202) = 1

GCD of 130, 397, 40, 202 is 1
