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 1,533,155, 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 | 1,533,155 | |
| -1 | -1,533,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,533,155.
Example:
1 x 1,533,155 = 1,533,155
and
-1 x -1,533,155 = 1,533,155
Notice both answers equal 1,533,155
With that explanation out of the way, let's continue. Next, we take the number 1,533,155 and divide it by 2:
1,533,155 ÷ 2 = 766,577.5
If the quotient is a whole number, then 2 and 766,577.5 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 | 1,533,155 | |
| -1 | -1,533,155 |
Now, we try dividing 1,533,155 by 3:
1,533,155 ÷ 3 = 511,051.6667
If the quotient is a whole number, then 3 and 511,051.6667 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 | 1,533,155 | |
| -1 | -1,533,155 |
Let's try dividing by 4:
1,533,155 ÷ 4 = 383,288.75
If the quotient is a whole number, then 4 and 383,288.75 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 | 1,533,155 | |
| -1 | 1,533,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 229 | 515 | 1,145 | 1,339 | 2,977 | 6,695 | 14,885 | 23,587 | 117,935 | 306,631 | 1,533,155 |
| -1 | -5 | -13 | -65 | -103 | -229 | -515 | -1,145 | -1,339 | -2,977 | -6,695 | -14,885 | -23,587 | -117,935 | -306,631 | -1,533,155 |
