Greatest Common Divisior

We found the divisors of 21, 62, 24 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 21, 62, 24 is 1.

Therefore, GCD of numbers 21, 62, 24 is 1

Given Input Data is 21, 62, 24

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 62 is 2 x 31

Prime Factorization of 24 is 2 x 2 x 2 x 3

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(21, 62) = 1302

GCD(21, 62) = ( 21 x 62 ) / 1302

GCD(21, 62) = 1302 / 1302

GCD(21, 62) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 24

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

LCM(1, 24) = 24

GCD(1, 24) = ( 1 x 24 ) / 24

GCD(1, 24) = 24 / 24

GCD(1, 24) = 1

GCD of 21, 62, 24 is 1
