1, 89

Greatest Common Divisior

We found the divisors of 35, 4, 20, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 35, 4, 20, 89 is 1.

Therefore, GCD of numbers 35, 4, 20, 89 is 1

Given Input Data is 35, 4, 20, 89

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

Prime Factorization of 35 is 5 x 7

Prime Factorization of 4 is 2 x 2

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 89 is 89

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(35, 4) = 140

GCD(35, 4) = ( 35 x 4 ) / 140

GCD(35, 4) = 140 / 140

GCD(35, 4) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

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

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 35, 4, 20, 89 is 1
