Greatest Common Divisior

We found the divisors of 61, 7, 89, 34 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 7, 89, 34 is 1.

Therefore, GCD of numbers 61, 7, 89, 34 is 1

Given Input Data is 61, 7, 89, 34

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

Prime Factorization of 61 is 61

Prime Factorization of 7 is 7

Prime Factorization of 89 is 89

Prime Factorization of 34 is 2 x 17

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(61, 7) = 427

GCD(61, 7) = ( 61 x 7 ) / 427

GCD(61, 7) = 427 / 427

GCD(61, 7) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 34

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

LCM(1, 34) = 34

GCD(1, 34) = ( 1 x 34 ) / 34

GCD(1, 34) = 34 / 34

GCD(1, 34) = 1

GCD of 61, 7, 89, 34 is 1
