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 1,172,015, 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 | 1,172,015 | |
| -1 | -1,172,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,172,015.
Example:
1 x 1,172,015 = 1,172,015
and
-1 x -1,172,015 = 1,172,015
Notice both answers equal 1,172,015
With that explanation out of the way, let's continue. Next, we take the number 1,172,015 and divide it by 2:
1,172,015 ÷ 2 = 586,007.5
If the quotient is a whole number, then 2 and 586,007.5 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 | 1,172,015 | |
| -1 | -1,172,015 |
Now, we try dividing 1,172,015 by 3:
1,172,015 ÷ 3 = 390,671.6667
If the quotient is a whole number, then 3 and 390,671.6667 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 | 1,172,015 | |
| -1 | -1,172,015 |
Let's try dividing by 4:
1,172,015 ÷ 4 = 293,003.75
If the quotient is a whole number, then 4 and 293,003.75 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 | 1,172,015 | |
| -1 | 1,172,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 73 | 95 | 169 | 247 | 365 | 845 | 949 | 1,235 | 1,387 | 3,211 | 4,745 | 6,935 | 12,337 | 16,055 | 18,031 | 61,685 | 90,155 | 234,403 | 1,172,015 |
| -1 | -5 | -13 | -19 | -65 | -73 | -95 | -169 | -247 | -365 | -845 | -949 | -1,235 | -1,387 | -3,211 | -4,745 | -6,935 | -12,337 | -16,055 | -18,031 | -61,685 | -90,155 | -234,403 | -1,172,015 |
