Greatest Common Divisior

We found the divisors of 62, 20, 87, 71 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 62, 20, 87, 71 is 1.

Therefore, GCD of numbers 62, 20, 87, 71 is 1

Given Input Data is 62, 20, 87, 71

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

Prime Factorization of 62 is 2 x 31

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 87 is 3 x 29

Prime Factorization of 71 is 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(62, 20) = 620

GCD(62, 20) = ( 62 x 20 ) / 620

GCD(62, 20) = 1240 / 620

GCD(62, 20) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 87

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

LCM(2, 87) = 174

GCD(2, 87) = ( 2 x 87 ) / 174

GCD(2, 87) = 174 / 174

GCD(2, 87) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

GCD of 62, 20, 87, 71 is 1
