Make use of GCD Calculator to determine the Greatest Common Divisor of 250, 445, 644 i.e. 1 largest integer that divides all the numbers equally.
GCD of 250, 445, 644 is 1
GCD(250, 445, 644) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 250, 445, 644 is 1
GCD(250, 445, 644) = 1
Given Input numbers are 250, 445, 644
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 89, 445
Divisors of 644
List of positive integer divisors of 644 that divides 644 without a remainder.
1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
Greatest Common Divisior
We found the divisors of 250, 445, 644 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 250, 445, 644 is 1.
Therefore, GCD of numbers 250, 445, 644 is 1
Given Input Data is 250, 445, 644
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 250 is 2 x 5 x 5 x 5
Prime Factorization of 445 is 5 x 89
Prime Factorization of 644 is 2 x 2 x 7 x 23
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(250, 445) = 22250
GCD(250, 445) = ( 250 x 445 ) / 22250
GCD(250, 445) = 111250 / 22250
GCD(250, 445) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 644
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 644) = 3220
GCD(5, 644) = ( 5 x 644 ) / 3220
GCD(5, 644) = 3220 / 3220
GCD(5, 644) = 1
GCD of 250, 445, 644 is 1
