We found the divisors of 47, 40, 79, 82 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 40, 79, 82 is 1.

Therefore, GCD of numbers 47, 40, 79, 82 is 1

Given Input Data is 47, 40, 79, 82

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

Prime Factorization of 47 is 47

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 79 is 79

Prime Factorization of 82 is 2 x 41

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(47, 40) = 1880

GCD(47, 40) = ( 47 x 40 ) / 1880

GCD(47, 40) = 1880 / 1880

GCD(47, 40) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 82

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

LCM(1, 82) = 82

GCD(1, 82) = ( 1 x 82 ) / 82

GCD(1, 82) = 82 / 82

GCD(1, 82) = 1

GCD of 47, 40, 79, 82 is 1
