Greatest Common Divisior

We found the divisors of 56, 48, 25, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 56, 48, 25, 61 is 1.

Therefore, GCD of numbers 56, 48, 25, 61 is 1

Given Input Data is 56, 48, 25, 61

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

Prime Factorization of 56 is 2 x 2 x 2 x 7

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

Prime Factorization of 25 is 5 x 5

Prime Factorization of 61 is 61

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(56, 48) = 336

GCD(56, 48) = ( 56 x 48 ) / 336

GCD(56, 48) = 2688 / 336

GCD(56, 48) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 25

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

LCM(8, 25) = 200

GCD(8, 25) = ( 8 x 25 ) / 200

GCD(8, 25) = 200 / 200

GCD(8, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 56, 48, 25, 61 is 1
