1, 919
Greatest Common Divisior
We found the divisors of 208, 864, 561, 919 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 208, 864, 561, 919 is 1.
Therefore, GCD of numbers 208, 864, 561, 919 is 1
Given Input Data is 208, 864, 561, 919
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13
Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime Factorization of 561 is 3 x 11 x 17
Prime Factorization of 919 is 919
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(208, 864) = 11232
GCD(208, 864) = ( 208 x 864 ) / 11232
GCD(208, 864) = 179712 / 11232
GCD(208, 864) = 16
Step2:
Here we consider the GCD from the above i.e. 16 as first number and the next as 561
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(16, 561) = 8976
GCD(16, 561) = ( 16 x 561 ) / 8976
GCD(16, 561) = 8976 / 8976
GCD(16, 561) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 919
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
GCD(1, 919) = 919 / 919
GCD(1, 919) = 1
GCD of 208, 864, 561, 919 is 1
