Greatest Common Divisior

We found the divisors of 62, 2, 23, 21 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 62, 2, 23, 21 is 1.

Therefore, GCD of numbers 62, 2, 23, 21 is 1

Given Input Data is 62, 2, 23, 21

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

Prime Factorization of 62 is 2 x 31

Prime Factorization of 2 is 2

Prime Factorization of 23 is 23

Prime Factorization of 21 is 3 x 7

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, 2) = 62

GCD(62, 2) = ( 62 x 2 ) / 62

GCD(62, 2) = 124 / 62

GCD(62, 2) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 23

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

LCM(2, 23) = 46

GCD(2, 23) = ( 2 x 23 ) / 46

GCD(2, 23) = 46 / 46

GCD(2, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

GCD of 62, 2, 23, 21 is 1
