Greatest Common Divisior

We found the divisors of 261, 270, 76, 811 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 261, 270, 76, 811 is 1.

Therefore, GCD of numbers 261, 270, 76, 811 is 1

Given Input Data is 261, 270, 76, 811

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

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 811 is 811

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(261, 270) = 7830

GCD(261, 270) = ( 261 x 270 ) / 7830

GCD(261, 270) = 70470 / 7830

GCD(261, 270) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 76

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

LCM(9, 76) = 684

GCD(9, 76) = ( 9 x 76 ) / 684

GCD(9, 76) = 684 / 684

GCD(9, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 261, 270, 76, 811 is 1
