1, 691
Greatest Common Divisior
We found the divisors of 663, 263, 640, 691 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 663, 263, 640, 691 is 1.
Therefore, GCD of numbers 663, 263, 640, 691 is 1
Given Input Data is 663, 263, 640, 691
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 663 is 3 x 13 x 17
Prime Factorization of 263 is 263
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 691 is 691
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(663, 263) = 174369
GCD(663, 263) = ( 663 x 263 ) / 174369
GCD(663, 263) = 174369 / 174369
GCD(663, 263) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 640
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
GCD(1, 640) = 640 / 640
GCD(1, 640) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 691
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
GCD(1, 691) = 691 / 691
GCD(1, 691) = 1
GCD of 663, 263, 640, 691 is 1
