Greatest Common Divisior

We found the divisors of 48, 11, 21, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 48, 11, 21, 56 is 1.

Therefore, GCD of numbers 48, 11, 21, 56 is 1

Given Input Data is 48, 11, 21, 56

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

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 11 is 11

Prime Factorization of 21 is 3 x 7

Prime Factorization of 56 is 2 x 2 x 2 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(48, 11) = 528

GCD(48, 11) = ( 48 x 11 ) / 528

GCD(48, 11) = 528 / 528

GCD(48, 11) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 48, 11, 21, 56 is 1
