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 1,488,905, 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 | 1,488,905 | |
| -1 | -1,488,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,488,905.
Example:
1 x 1,488,905 = 1,488,905
and
-1 x -1,488,905 = 1,488,905
Notice both answers equal 1,488,905
With that explanation out of the way, let's continue. Next, we take the number 1,488,905 and divide it by 2:
1,488,905 ÷ 2 = 744,452.5
If the quotient is a whole number, then 2 and 744,452.5 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 | 1,488,905 | |
| -1 | -1,488,905 |
Now, we try dividing 1,488,905 by 3:
1,488,905 ÷ 3 = 496,301.6667
If the quotient is a whole number, then 3 and 496,301.6667 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 | 1,488,905 | |
| -1 | -1,488,905 |
Let's try dividing by 4:
1,488,905 ÷ 4 = 372,226.25
If the quotient is a whole number, then 4 and 372,226.25 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 | 1,488,905 | |
| -1 | 1,488,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 107 | 115 | 121 | 253 | 535 | 605 | 1,177 | 1,265 | 2,461 | 2,783 | 5,885 | 12,305 | 12,947 | 13,915 | 27,071 | 64,735 | 135,355 | 297,781 | 1,488,905 |
| -1 | -5 | -11 | -23 | -55 | -107 | -115 | -121 | -253 | -535 | -605 | -1,177 | -1,265 | -2,461 | -2,783 | -5,885 | -12,305 | -12,947 | -13,915 | -27,071 | -64,735 | -135,355 | -297,781 | -1,488,905 |
