We found the divisors of 43, 8, 11, 28 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 43, 8, 11, 28 is 1.

Therefore, GCD of numbers 43, 8, 11, 28 is 1

Given Input Data is 43, 8, 11, 28

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

Prime Factorization of 43 is 43

Prime Factorization of 8 is 2 x 2 x 2

Prime Factorization of 11 is 11

Prime Factorization of 28 is 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(43, 8) = 344

GCD(43, 8) = ( 43 x 8 ) / 344

GCD(43, 8) = 344 / 344

GCD(43, 8) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 11

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

LCM(1, 11) = 11

GCD(1, 11) = ( 1 x 11 ) / 11

GCD(1, 11) = 11 / 11

GCD(1, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

GCD of 43, 8, 11, 28 is 1
