Greatest Common Divisior

We found the divisors of 48, 21, 72, 92 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 48, 21, 72, 92 is 1.

Therefore, GCD of numbers 48, 21, 72, 92 is 1

Given Input Data is 48, 21, 72, 92

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 21 is 3 x 7

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 92 is 2 x 2 x 23

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, 21) = 336

GCD(48, 21) = ( 48 x 21 ) / 336

GCD(48, 21) = 1008 / 336

GCD(48, 21) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 72

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

LCM(3, 72) = 72

GCD(3, 72) = ( 3 x 72 ) / 72

GCD(3, 72) = 216 / 72

GCD(3, 72) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 92

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

LCM(3, 92) = 276

GCD(3, 92) = ( 3 x 92 ) / 276

GCD(3, 92) = 276 / 276

GCD(3, 92) = 1

GCD of 48, 21, 72, 92 is 1
