Greatest Common Divisior

We found the divisors of 129, 159, 70, 710 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 129, 159, 70, 710 is 1.

Therefore, GCD of numbers 129, 159, 70, 710 is 1

Given Input Data is 129, 159, 70, 710

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 159 is 3 x 53

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 710 is 2 x 5 x 71

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(129, 159) = 6837

GCD(129, 159) = ( 129 x 159 ) / 6837

GCD(129, 159) = 20511 / 6837

GCD(129, 159) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 70

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

LCM(3, 70) = 210

GCD(3, 70) = ( 3 x 70 ) / 210

GCD(3, 70) = 210 / 210

GCD(3, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 710

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

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

GCD(1, 710) = 710 / 710

GCD(1, 710) = 1

GCD of 129, 159, 70, 710 is 1
