Greatest Common Divisior

We found the divisors of 66, 71, 84, 58 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 66, 71, 84, 58 is 1.

Therefore, GCD of numbers 66, 71, 84, 58 is 1

Given Input Data is 66, 71, 84, 58

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 71 is 71

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 58 is 2 x 29

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(66, 71) = 4686

GCD(66, 71) = ( 66 x 71 ) / 4686

GCD(66, 71) = 4686 / 4686

GCD(66, 71) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 84

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

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

GCD(1, 84) = 84 / 84

GCD(1, 84) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 58

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

LCM(1, 58) = 58

GCD(1, 58) = ( 1 x 58 ) / 58

GCD(1, 58) = 58 / 58

GCD(1, 58) = 1

GCD of 66, 71, 84, 58 is 1
