Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 623,441, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 623,441 | |
| -1 | -623,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 623,441.
Example:
1 x 623,441 = 623,441
and
-1 x -623,441 = 623,441
Notice both answers equal 623,441
With that explanation out of the way, let's continue. Next, we take the number 623,441 and divide it by 2:
623,441 ÷ 2 = 311,720.5
If the quotient is a whole number, then 2 and 311,720.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 623,441 | |
| -1 | -623,441 |
Now, we try dividing 623,441 by 3:
623,441 ÷ 3 = 207,813.6667
If the quotient is a whole number, then 3 and 207,813.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 623,441 | |
| -1 | -623,441 |
Let's try dividing by 4:
623,441 ÷ 4 = 155,860.25
If the quotient is a whole number, then 4 and 155,860.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 623,441 | |
| -1 | 623,441 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 31 | 91 | 119 | 169 | 217 | 221 | 403 | 527 | 1,183 | 1,547 | 2,821 | 2,873 | 3,689 | 5,239 | 6,851 | 20,111 | 36,673 | 47,957 | 89,063 | 623,441 |
| -1 | -7 | -13 | -17 | -31 | -91 | -119 | -169 | -217 | -221 | -403 | -527 | -1,183 | -1,547 | -2,821 | -2,873 | -3,689 | -5,239 | -6,851 | -20,111 | -36,673 | -47,957 | -89,063 | -623,441 |
