Greatest Common Divisior
We found the divisors of 263, 784, 438, 491 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 263, 784, 438, 491 is 1.
Therefore, GCD of numbers 263, 784, 438, 491 is 1
Given Input Data is 263, 784, 438, 491
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 263 is 263
Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7
Prime Factorization of 438 is 2 x 3 x 73
Prime Factorization of 491 is 491
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(263, 784) = 206192
GCD(263, 784) = ( 263 x 784 ) / 206192
GCD(263, 784) = 206192 / 206192
GCD(263, 784) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 438
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
GCD(1, 438) = 438 / 438
GCD(1, 438) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 491
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
GCD(1, 491) = 491 / 491
GCD(1, 491) = 1
GCD of 263, 784, 438, 491 is 1
