Make use of GCD Calculator to determine the Greatest Common Divisor of 687, 248, 609 i.e. 1 largest integer that divides all the numbers equally.
GCD of 687, 248, 609 is 1
GCD(687, 248, 609) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 687, 248, 609 is 1
GCD(687, 248, 609) = 1
Given Input numbers are 687, 248, 609
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 8, 31, 62, 124, 248
Divisors of 609
List of positive integer divisors of 609 that divides 609 without a remainder.
1, 3, 7, 21, 29, 87, 203, 609
Greatest Common Divisior
We found the divisors of 687, 248, 609 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 687, 248, 609 is 1.
Therefore, GCD of numbers 687, 248, 609 is 1
Given Input Data is 687, 248, 609
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 687 is 3 x 229
Prime Factorization of 248 is 2 x 2 x 2 x 31
Prime Factorization of 609 is 3 x 7 x 29
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(687, 248) = 170376
GCD(687, 248) = ( 687 x 248 ) / 170376
GCD(687, 248) = 170376 / 170376
GCD(687, 248) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 609
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
GCD(1, 609) = 609 / 609
GCD(1, 609) = 1
GCD of 687, 248, 609 is 1
