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 17,606,729, 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 | 17,606,729 | |
| -1 | -17,606,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,606,729.
Example:
1 x 17,606,729 = 17,606,729
and
-1 x -17,606,729 = 17,606,729
Notice both answers equal 17,606,729
With that explanation out of the way, let's continue. Next, we take the number 17,606,729 and divide it by 2:
17,606,729 ÷ 2 = 8,803,364.5
If the quotient is a whole number, then 2 and 8,803,364.5 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 | 17,606,729 | |
| -1 | -17,606,729 |
Now, we try dividing 17,606,729 by 3:
17,606,729 ÷ 3 = 5,868,909.6667
If the quotient is a whole number, then 3 and 5,868,909.6667 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 | 17,606,729 | |
| -1 | -17,606,729 |
Let's try dividing by 4:
17,606,729 ÷ 4 = 4,401,682.25
If the quotient is a whole number, then 4 and 4,401,682.25 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 | 17,606,729 | |
| -1 | 17,606,729 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 67 | 173 | 217 | 469 | 1,211 | 1,519 | 2,077 | 3,283 | 5,363 | 8,477 | 11,591 | 14,539 | 37,541 | 81,137 | 101,773 | 262,787 | 359,321 | 567,959 | 2,515,247 | 17,606,729 |
| -1 | -7 | -31 | -49 | -67 | -173 | -217 | -469 | -1,211 | -1,519 | -2,077 | -3,283 | -5,363 | -8,477 | -11,591 | -14,539 | -37,541 | -81,137 | -101,773 | -262,787 | -359,321 | -567,959 | -2,515,247 | -17,606,729 |
