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 1,487,629, 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 | 1,487,629 | |
| -1 | -1,487,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,487,629.
Example:
1 x 1,487,629 = 1,487,629
and
-1 x -1,487,629 = 1,487,629
Notice both answers equal 1,487,629
With that explanation out of the way, let's continue. Next, we take the number 1,487,629 and divide it by 2:
1,487,629 ÷ 2 = 743,814.5
If the quotient is a whole number, then 2 and 743,814.5 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 | 1,487,629 | |
| -1 | -1,487,629 |
Now, we try dividing 1,487,629 by 3:
1,487,629 ÷ 3 = 495,876.3333
If the quotient is a whole number, then 3 and 495,876.3333 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 | 1,487,629 | |
| -1 | -1,487,629 |
Let's try dividing by 4:
1,487,629 ÷ 4 = 371,907.25
If the quotient is a whole number, then 4 and 371,907.25 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 | 1,487,629 | |
| -1 | 1,487,629 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 101 | 103 | 143 | 1,111 | 1,133 | 1,313 | 1,339 | 10,403 | 14,443 | 14,729 | 114,433 | 135,239 | 1,487,629 |
| -1 | -11 | -13 | -101 | -103 | -143 | -1,111 | -1,133 | -1,313 | -1,339 | -10,403 | -14,443 | -14,729 | -114,433 | -135,239 | -1,487,629 |
