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 1,187,329, 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 | 1,187,329 | |
| -1 | -1,187,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,187,329.
Example:
1 x 1,187,329 = 1,187,329
and
-1 x -1,187,329 = 1,187,329
Notice both answers equal 1,187,329
With that explanation out of the way, let's continue. Next, we take the number 1,187,329 and divide it by 2:
1,187,329 ÷ 2 = 593,664.5
If the quotient is a whole number, then 2 and 593,664.5 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 | 1,187,329 | |
| -1 | -1,187,329 |
Now, we try dividing 1,187,329 by 3:
1,187,329 ÷ 3 = 395,776.3333
If the quotient is a whole number, then 3 and 395,776.3333 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 | 1,187,329 | |
| -1 | -1,187,329 |
Let's try dividing by 4:
1,187,329 ÷ 4 = 296,832.25
If the quotient is a whole number, then 4 and 296,832.25 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 | 1,187,329 | |
| -1 | 1,187,329 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 23 | 143 | 209 | 247 | 253 | 299 | 361 | 437 | 2,717 | 3,289 | 3,971 | 4,693 | 4,807 | 5,681 | 8,303 | 51,623 | 62,491 | 91,333 | 107,939 | 1,187,329 |
| -1 | -11 | -13 | -19 | -23 | -143 | -209 | -247 | -253 | -299 | -361 | -437 | -2,717 | -3,289 | -3,971 | -4,693 | -4,807 | -5,681 | -8,303 | -51,623 | -62,491 | -91,333 | -107,939 | -1,187,329 |
