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 1,144,015, 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 | 1,144,015 | |
| -1 | -1,144,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,144,015.
Example:
1 x 1,144,015 = 1,144,015
and
-1 x -1,144,015 = 1,144,015
Notice both answers equal 1,144,015
With that explanation out of the way, let's continue. Next, we take the number 1,144,015 and divide it by 2:
1,144,015 ÷ 2 = 572,007.5
If the quotient is a whole number, then 2 and 572,007.5 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 | 1,144,015 | |
| -1 | -1,144,015 |
Now, we try dividing 1,144,015 by 3:
1,144,015 ÷ 3 = 381,338.3333
If the quotient is a whole number, then 3 and 381,338.3333 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 | 1,144,015 | |
| -1 | -1,144,015 |
Let's try dividing by 4:
1,144,015 ÷ 4 = 286,003.75
If the quotient is a whole number, then 4 and 286,003.75 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 | 1,144,015 | |
| -1 | 1,144,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 313 | 731 | 1,565 | 3,655 | 5,321 | 13,459 | 26,605 | 67,295 | 228,803 | 1,144,015 |
| -1 | -5 | -17 | -43 | -85 | -215 | -313 | -731 | -1,565 | -3,655 | -5,321 | -13,459 | -26,605 | -67,295 | -228,803 | -1,144,015 |
