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 17,053,421, 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 | 17,053,421 | |
| -1 | -17,053,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,053,421.
Example:
1 x 17,053,421 = 17,053,421
and
-1 x -17,053,421 = 17,053,421
Notice both answers equal 17,053,421
With that explanation out of the way, let's continue. Next, we take the number 17,053,421 and divide it by 2:
17,053,421 ÷ 2 = 8,526,710.5
If the quotient is a whole number, then 2 and 8,526,710.5 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 | 17,053,421 | |
| -1 | -17,053,421 |
Now, we try dividing 17,053,421 by 3:
17,053,421 ÷ 3 = 5,684,473.6667
If the quotient is a whole number, then 3 and 5,684,473.6667 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 | 17,053,421 | |
| -1 | -17,053,421 |
Let's try dividing by 4:
17,053,421 ÷ 4 = 4,263,355.25
If the quotient is a whole number, then 4 and 4,263,355.25 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 | 17,053,421 | |
| -1 | 17,053,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 49 | 77 | 203 | 319 | 539 | 1,091 | 1,421 | 2,233 | 7,637 | 12,001 | 15,631 | 31,639 | 53,459 | 84,007 | 221,473 | 348,029 | 588,049 | 1,550,311 | 2,436,203 | 17,053,421 |
| -1 | -7 | -11 | -29 | -49 | -77 | -203 | -319 | -539 | -1,091 | -1,421 | -2,233 | -7,637 | -12,001 | -15,631 | -31,639 | -53,459 | -84,007 | -221,473 | -348,029 | -588,049 | -1,550,311 | -2,436,203 | -17,053,421 |
