Greatest Common Divisior

We found the divisors of 61, 73, 86, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 73, 86, 47 is 1.

Therefore, GCD of numbers 61, 73, 86, 47 is 1

Given Input Data is 61, 73, 86, 47

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

Prime Factorization of 61 is 61

Prime Factorization of 73 is 73

Prime Factorization of 86 is 2 x 43

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(61, 73) = 4453

GCD(61, 73) = ( 61 x 73 ) / 4453

GCD(61, 73) = 4453 / 4453

GCD(61, 73) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 86

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

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

GCD(1, 86) = 86 / 86

GCD(1, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 47

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

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

GCD(1, 47) = 47 / 47

GCD(1, 47) = 1

GCD of 61, 73, 86, 47 is 1
