Greatest Common Divisior

We found the divisors of 32, 5, 66, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 5, 66, 61 is 1.

Therefore, GCD of numbers 32, 5, 66, 61 is 1

Given Input Data is 32, 5, 66, 61

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

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 5 is 5

Prime Factorization of 66 is 2 x 3 x 11

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(32, 5) = 160

GCD(32, 5) = ( 32 x 5 ) / 160

GCD(32, 5) = 160 / 160

GCD(32, 5) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 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 32, 5, 66, 61 is 1
