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 1,439,815, 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 | 1,439,815 | |
| -1 | -1,439,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,439,815.
Example:
1 x 1,439,815 = 1,439,815
and
-1 x -1,439,815 = 1,439,815
Notice both answers equal 1,439,815
With that explanation out of the way, let's continue. Next, we take the number 1,439,815 and divide it by 2:
1,439,815 ÷ 2 = 719,907.5
If the quotient is a whole number, then 2 and 719,907.5 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 | 1,439,815 | |
| -1 | -1,439,815 |
Now, we try dividing 1,439,815 by 3:
1,439,815 ÷ 3 = 479,938.3333
If the quotient is a whole number, then 3 and 479,938.3333 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 | 1,439,815 | |
| -1 | -1,439,815 |
Let's try dividing by 4:
1,439,815 ÷ 4 = 359,953.75
If the quotient is a whole number, then 4 and 359,953.75 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 | 1,439,815 | |
| -1 | 1,439,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 1,303 | 6,515 | 16,939 | 22,151 | 84,695 | 110,755 | 287,963 | 1,439,815 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -1,303 | -6,515 | -16,939 | -22,151 | -84,695 | -110,755 | -287,963 | -1,439,815 |
