Greatest Common Divisior

We found the divisors of 42, 8, 43, 44 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 42, 8, 43, 44 is 1.

Therefore, GCD of numbers 42, 8, 43, 44 is 1

Given Input Data is 42, 8, 43, 44

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

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 8 is 2 x 2 x 2

Prime Factorization of 43 is 43

Prime Factorization of 44 is 2 x 2 x 11

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(42, 8) = 168

GCD(42, 8) = ( 42 x 8 ) / 168

GCD(42, 8) = 336 / 168

GCD(42, 8) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 43

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

LCM(2, 43) = 86

GCD(2, 43) = ( 2 x 43 ) / 86

GCD(2, 43) = 86 / 86

GCD(2, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 44

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

LCM(1, 44) = 44

GCD(1, 44) = ( 1 x 44 ) / 44

GCD(1, 44) = 44 / 44

GCD(1, 44) = 1

GCD of 42, 8, 43, 44 is 1
