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 1,563,155, 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 | 1,563,155 | |
| -1 | -1,563,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,563,155.
Example:
1 x 1,563,155 = 1,563,155
and
-1 x -1,563,155 = 1,563,155
Notice both answers equal 1,563,155
With that explanation out of the way, let's continue. Next, we take the number 1,563,155 and divide it by 2:
1,563,155 ÷ 2 = 781,577.5
If the quotient is a whole number, then 2 and 781,577.5 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 | 1,563,155 | |
| -1 | -1,563,155 |
Now, we try dividing 1,563,155 by 3:
1,563,155 ÷ 3 = 521,051.6667
If the quotient is a whole number, then 3 and 521,051.6667 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 | 1,563,155 | |
| -1 | -1,563,155 |
Let's try dividing by 4:
1,563,155 ÷ 4 = 390,788.75
If the quotient is a whole number, then 4 and 390,788.75 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 | 1,563,155 | |
| -1 | 1,563,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 97 | 293 | 485 | 1,067 | 1,465 | 3,223 | 5,335 | 16,115 | 28,421 | 142,105 | 312,631 | 1,563,155 |
| -1 | -5 | -11 | -55 | -97 | -293 | -485 | -1,067 | -1,465 | -3,223 | -5,335 | -16,115 | -28,421 | -142,105 | -312,631 | -1,563,155 |
