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 1,563,055, 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 | 1,563,055 | |
| -1 | -1,563,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,563,055.
Example:
1 x 1,563,055 = 1,563,055
and
-1 x -1,563,055 = 1,563,055
Notice both answers equal 1,563,055
With that explanation out of the way, let's continue. Next, we take the number 1,563,055 and divide it by 2:
1,563,055 ÷ 2 = 781,527.5
If the quotient is a whole number, then 2 and 781,527.5 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 | 1,563,055 | |
| -1 | -1,563,055 |
Now, we try dividing 1,563,055 by 3:
1,563,055 ÷ 3 = 521,018.3333
If the quotient is a whole number, then 3 and 521,018.3333 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 | 1,563,055 | |
| -1 | -1,563,055 |
Let's try dividing by 4:
1,563,055 ÷ 4 = 390,763.75
If the quotient is a whole number, then 4 and 390,763.75 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 | 1,563,055 | |
| -1 | 1,563,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 139 | 173 | 695 | 865 | 1,807 | 2,249 | 9,035 | 11,245 | 24,047 | 120,235 | 312,611 | 1,563,055 |
| -1 | -5 | -13 | -65 | -139 | -173 | -695 | -865 | -1,807 | -2,249 | -9,035 | -11,245 | -24,047 | -120,235 | -312,611 | -1,563,055 |
