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 1,147,315, 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 | 1,147,315 | |
| -1 | -1,147,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,147,315.
Example:
1 x 1,147,315 = 1,147,315
and
-1 x -1,147,315 = 1,147,315
Notice both answers equal 1,147,315
With that explanation out of the way, let's continue. Next, we take the number 1,147,315 and divide it by 2:
1,147,315 ÷ 2 = 573,657.5
If the quotient is a whole number, then 2 and 573,657.5 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 | 1,147,315 | |
| -1 | -1,147,315 |
Now, we try dividing 1,147,315 by 3:
1,147,315 ÷ 3 = 382,438.3333
If the quotient is a whole number, then 3 and 382,438.3333 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 | 1,147,315 | |
| -1 | -1,147,315 |
Let's try dividing by 4:
1,147,315 ÷ 4 = 286,828.75
If the quotient is a whole number, then 4 and 286,828.75 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 | 1,147,315 | |
| -1 | 1,147,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 929 | 1,235 | 4,645 | 12,077 | 17,651 | 60,385 | 88,255 | 229,463 | 1,147,315 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -929 | -1,235 | -4,645 | -12,077 | -17,651 | -60,385 | -88,255 | -229,463 | -1,147,315 |
