We found the divisors of 16, 86, 68, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 16, 86, 68, 47 is 1.

Therefore, GCD of numbers 16, 86, 68, 47 is 1

Given Input Data is 16, 86, 68, 47

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

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 86 is 2 x 43

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 47 is 47

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(16, 86) = 688

GCD(16, 86) = ( 16 x 86 ) / 688

GCD(16, 86) = 1376 / 688

GCD(16, 86) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 68

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

LCM(2, 68) = 68

GCD(2, 68) = ( 2 x 68 ) / 68

GCD(2, 68) = 136 / 68

GCD(2, 68) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 47

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

LCM(2, 47) = 94

GCD(2, 47) = ( 2 x 47 ) / 94

GCD(2, 47) = 94 / 94

GCD(2, 47) = 1

GCD of 16, 86, 68, 47 is 1
