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 1,369,459, 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 | 1,369,459 | |
| -1 | -1,369,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,369,459.
Example:
1 x 1,369,459 = 1,369,459
and
-1 x -1,369,459 = 1,369,459
Notice both answers equal 1,369,459
With that explanation out of the way, let's continue. Next, we take the number 1,369,459 and divide it by 2:
1,369,459 ÷ 2 = 684,729.5
If the quotient is a whole number, then 2 and 684,729.5 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 | 1,369,459 | |
| -1 | -1,369,459 |
Now, we try dividing 1,369,459 by 3:
1,369,459 ÷ 3 = 456,486.3333
If the quotient is a whole number, then 3 and 456,486.3333 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 | 1,369,459 | |
| -1 | -1,369,459 |
Let's try dividing by 4:
1,369,459 ÷ 4 = 342,364.75
If the quotient is a whole number, then 4 and 342,364.75 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 | 1,369,459 | |
| -1 | 1,369,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 101 | 149 | 707 | 1,043 | 1,313 | 1,937 | 9,191 | 13,559 | 15,049 | 105,343 | 195,637 | 1,369,459 |
| -1 | -7 | -13 | -91 | -101 | -149 | -707 | -1,043 | -1,313 | -1,937 | -9,191 | -13,559 | -15,049 | -105,343 | -195,637 | -1,369,459 |
