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 17,544,415, 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 | 17,544,415 | |
| -1 | -17,544,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,544,415.
Example:
1 x 17,544,415 = 17,544,415
and
-1 x -17,544,415 = 17,544,415
Notice both answers equal 17,544,415
With that explanation out of the way, let's continue. Next, we take the number 17,544,415 and divide it by 2:
17,544,415 ÷ 2 = 8,772,207.5
If the quotient is a whole number, then 2 and 8,772,207.5 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 | 17,544,415 | |
| -1 | -17,544,415 |
Now, we try dividing 17,544,415 by 3:
17,544,415 ÷ 3 = 5,848,138.3333
If the quotient is a whole number, then 3 and 5,848,138.3333 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 | 17,544,415 | |
| -1 | -17,544,415 |
Let's try dividing by 4:
17,544,415 ÷ 4 = 4,386,103.75
If the quotient is a whole number, then 4 and 4,386,103.75 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 | 17,544,415 | |
| -1 | 17,544,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 3,947 | 4,445 | 19,735 | 27,629 | 138,145 | 501,269 | 2,506,345 | 3,508,883 | 17,544,415 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -3,947 | -4,445 | -19,735 | -27,629 | -138,145 | -501,269 | -2,506,345 | -3,508,883 | -17,544,415 |
