Greatest Common Divisior
We found the divisors of 206, 287, 644, 176 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 206, 287, 644, 176 is 1.
Therefore, GCD of numbers 206, 287, 644, 176 is 1
Given Input Data is 206, 287, 644, 176
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 206 is 2 x 103
Prime Factorization of 287 is 7 x 41
Prime Factorization of 644 is 2 x 2 x 7 x 23
Prime Factorization of 176 is 2 x 2 x 2 x 2 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(206, 287) = 59122
GCD(206, 287) = ( 206 x 287 ) / 59122
GCD(206, 287) = 59122 / 59122
GCD(206, 287) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 644
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
GCD(1, 644) = 644 / 644
GCD(1, 644) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 176
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 176) = 176
GCD(1, 176) = ( 1 x 176 ) / 176
GCD(1, 176) = 176 / 176
GCD(1, 176) = 1
GCD of 206, 287, 644, 176 is 1
