Greatest Common Divisior
We found the divisors of 978, 820, 81, 264 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 978, 820, 81, 264 is 1.
Therefore, GCD of numbers 978, 820, 81, 264 is 1
Given Input Data is 978, 820, 81, 264
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 978 is 2 x 3 x 163
Prime Factorization of 820 is 2 x 2 x 5 x 41
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 264 is 2 x 2 x 2 x 3 x 11
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(978, 820) = 400980
GCD(978, 820) = ( 978 x 820 ) / 400980
GCD(978, 820) = 801960 / 400980
GCD(978, 820) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
GCD(2, 81) = 162 / 162
GCD(2, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 264
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 264) = 264
GCD(1, 264) = ( 1 x 264 ) / 264
GCD(1, 264) = 264 / 264
GCD(1, 264) = 1
GCD of 978, 820, 81, 264 is 1
