Greatest Common Divisior

We found the divisors of 53, 4, 56, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 53, 4, 56, 61 is 1.

Therefore, GCD of numbers 53, 4, 56, 61 is 1

Given Input Data is 53, 4, 56, 61

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

Prime Factorization of 53 is 53

Prime Factorization of 4 is 2 x 2

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

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(53, 4) = 212

GCD(53, 4) = ( 53 x 4 ) / 212

GCD(53, 4) = 212 / 212

GCD(53, 4) = 1

Step2:

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

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 53, 4, 56, 61 is 1
