Greatest Common Divisior

We found the divisors of 33, 4, 77, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 33, 4, 77, 64 is 1.

Therefore, GCD of numbers 33, 4, 77, 64 is 1

Given Input Data is 33, 4, 77, 64

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 4 is 2 x 2

Prime Factorization of 77 is 7 x 11

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

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(33, 4) = 132

GCD(33, 4) = ( 33 x 4 ) / 132

GCD(33, 4) = 132 / 132

GCD(33, 4) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

Step3:

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

GCD of 33, 4, 77, 64 is 1
