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 17,671,225, 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 | 17,671,225 | |
| -1 | -17,671,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,671,225.
Example:
1 x 17,671,225 = 17,671,225
and
-1 x -17,671,225 = 17,671,225
Notice both answers equal 17,671,225
With that explanation out of the way, let's continue. Next, we take the number 17,671,225 and divide it by 2:
17,671,225 ÷ 2 = 8,835,612.5
If the quotient is a whole number, then 2 and 8,835,612.5 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 | 17,671,225 | |
| -1 | -17,671,225 |
Now, we try dividing 17,671,225 by 3:
17,671,225 ÷ 3 = 5,890,408.3333
If the quotient is a whole number, then 3 and 5,890,408.3333 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 | 17,671,225 | |
| -1 | -17,671,225 |
Let's try dividing by 4:
17,671,225 ÷ 4 = 4,417,806.25
If the quotient is a whole number, then 4 and 4,417,806.25 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 | 17,671,225 | |
| -1 | 17,671,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 3,575 | 4,943 | 24,715 | 54,373 | 64,259 | 123,575 | 271,865 | 321,295 | 706,849 | 1,359,325 | 1,606,475 | 3,534,245 | 17,671,225 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -3,575 | -4,943 | -24,715 | -54,373 | -64,259 | -123,575 | -271,865 | -321,295 | -706,849 | -1,359,325 | -1,606,475 | -3,534,245 | -17,671,225 |
