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 1,440,043, 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 | 1,440,043 | |
| -1 | -1,440,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,440,043.
Example:
1 x 1,440,043 = 1,440,043
and
-1 x -1,440,043 = 1,440,043
Notice both answers equal 1,440,043
With that explanation out of the way, let's continue. Next, we take the number 1,440,043 and divide it by 2:
1,440,043 ÷ 2 = 720,021.5
If the quotient is a whole number, then 2 and 720,021.5 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 | 1,440,043 | |
| -1 | -1,440,043 |
Now, we try dividing 1,440,043 by 3:
1,440,043 ÷ 3 = 480,014.3333
If the quotient is a whole number, then 3 and 480,014.3333 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 | 1,440,043 | |
| -1 | -1,440,043 |
Let's try dividing by 4:
1,440,043 ÷ 4 = 360,010.75
If the quotient is a whole number, then 4 and 360,010.75 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 | 1,440,043 | |
| -1 | 1,440,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 41 | 103 | 341 | 451 | 1,133 | 1,271 | 3,193 | 4,223 | 13,981 | 35,123 | 46,453 | 130,913 | 1,440,043 |
| -1 | -11 | -31 | -41 | -103 | -341 | -451 | -1,133 | -1,271 | -3,193 | -4,223 | -13,981 | -35,123 | -46,453 | -130,913 | -1,440,043 |
