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 17,042,053, 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 | 17,042,053 | |
| -1 | -17,042,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,042,053.
Example:
1 x 17,042,053 = 17,042,053
and
-1 x -17,042,053 = 17,042,053
Notice both answers equal 17,042,053
With that explanation out of the way, let's continue. Next, we take the number 17,042,053 and divide it by 2:
17,042,053 ÷ 2 = 8,521,026.5
If the quotient is a whole number, then 2 and 8,521,026.5 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 | 17,042,053 | |
| -1 | -17,042,053 |
Now, we try dividing 17,042,053 by 3:
17,042,053 ÷ 3 = 5,680,684.3333
If the quotient is a whole number, then 3 and 5,680,684.3333 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 | 17,042,053 | |
| -1 | -17,042,053 |
Let's try dividing by 4:
17,042,053 ÷ 4 = 4,260,513.25
If the quotient is a whole number, then 4 and 4,260,513.25 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 | 17,042,053 | |
| -1 | 17,042,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 67 | 179 | 203 | 469 | 1,253 | 1,421 | 1,943 | 3,283 | 5,191 | 8,771 | 11,993 | 13,601 | 36,337 | 83,951 | 95,207 | 254,359 | 347,797 | 587,657 | 2,434,579 | 17,042,053 |
| -1 | -7 | -29 | -49 | -67 | -179 | -203 | -469 | -1,253 | -1,421 | -1,943 | -3,283 | -5,191 | -8,771 | -11,993 | -13,601 | -36,337 | -83,951 | -95,207 | -254,359 | -347,797 | -587,657 | -2,434,579 | -17,042,053 |
