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 1,147,385, 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 | 1,147,385 | |
| -1 | -1,147,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,147,385.
Example:
1 x 1,147,385 = 1,147,385
and
-1 x -1,147,385 = 1,147,385
Notice both answers equal 1,147,385
With that explanation out of the way, let's continue. Next, we take the number 1,147,385 and divide it by 2:
1,147,385 ÷ 2 = 573,692.5
If the quotient is a whole number, then 2 and 573,692.5 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 | 1,147,385 | |
| -1 | -1,147,385 |
Now, we try dividing 1,147,385 by 3:
1,147,385 ÷ 3 = 382,461.6667
If the quotient is a whole number, then 3 and 382,461.6667 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 | 1,147,385 | |
| -1 | -1,147,385 |
Let's try dividing by 4:
1,147,385 ÷ 4 = 286,846.25
If the quotient is a whole number, then 4 and 286,846.25 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 | 1,147,385 | |
| -1 | 1,147,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 193 | 205 | 965 | 1,189 | 5,597 | 5,945 | 7,913 | 27,985 | 39,565 | 229,477 | 1,147,385 |
| -1 | -5 | -29 | -41 | -145 | -193 | -205 | -965 | -1,189 | -5,597 | -5,945 | -7,913 | -27,985 | -39,565 | -229,477 | -1,147,385 |
