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 17,384,731, 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 | 17,384,731 | |
| -1 | -17,384,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,384,731.
Example:
1 x 17,384,731 = 17,384,731
and
-1 x -17,384,731 = 17,384,731
Notice both answers equal 17,384,731
With that explanation out of the way, let's continue. Next, we take the number 17,384,731 and divide it by 2:
17,384,731 ÷ 2 = 8,692,365.5
If the quotient is a whole number, then 2 and 8,692,365.5 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 | 17,384,731 | |
| -1 | -17,384,731 |
Now, we try dividing 17,384,731 by 3:
17,384,731 ÷ 3 = 5,794,910.3333
If the quotient is a whole number, then 3 and 5,794,910.3333 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 | 17,384,731 | |
| -1 | -17,384,731 |
Let's try dividing by 4:
17,384,731 ÷ 4 = 4,346,182.75
If the quotient is a whole number, then 4 and 4,346,182.75 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 | 17,384,731 | |
| -1 | 17,384,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 511 | 949 | 2,617 | 6,643 | 18,319 | 34,021 | 191,041 | 238,147 | 1,337,287 | 2,483,533 | 17,384,731 |
| -1 | -7 | -13 | -73 | -91 | -511 | -949 | -2,617 | -6,643 | -18,319 | -34,021 | -191,041 | -238,147 | -1,337,287 | -2,483,533 | -17,384,731 |
