We found the divisors of 53, 48, 51, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 53, 48, 51, 20 is 1.

Therefore, GCD of numbers 53, 48, 51, 20 is 1

Given Input Data is 53, 48, 51, 20

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

Prime Factorization of 53 is 53

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 20 is 2 x 2 x 5

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, 48) = 2544

GCD(53, 48) = ( 53 x 48 ) / 2544

GCD(53, 48) = 2544 / 2544

GCD(53, 48) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 51

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

LCM(1, 51) = 51

GCD(1, 51) = ( 1 x 51 ) / 51

GCD(1, 51) = 51 / 51

GCD(1, 51) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 53, 48, 51, 20 is 1
