Greatest Common Divisior

We found the divisors of 47, 55, 64, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 55, 64, 61 is 1.

Therefore, GCD of numbers 47, 55, 64, 61 is 1

Given Input Data is 47, 55, 64, 61

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

Prime Factorization of 47 is 47

Prime Factorization of 55 is 5 x 11

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 61 is 61

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, 55) = 2585

GCD(47, 55) = ( 47 x 55 ) / 2585

GCD(47, 55) = 2585 / 2585

GCD(47, 55) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 64

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

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

GCD(1, 64) = 64 / 64

GCD(1, 64) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 47, 55, 64, 61 is 1
