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 17,573,155, 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 | 17,573,155 | |
| -1 | -17,573,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,573,155.
Example:
1 x 17,573,155 = 17,573,155
and
-1 x -17,573,155 = 17,573,155
Notice both answers equal 17,573,155
With that explanation out of the way, let's continue. Next, we take the number 17,573,155 and divide it by 2:
17,573,155 ÷ 2 = 8,786,577.5
If the quotient is a whole number, then 2 and 8,786,577.5 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 | 17,573,155 | |
| -1 | -17,573,155 |
Now, we try dividing 17,573,155 by 3:
17,573,155 ÷ 3 = 5,857,718.3333
If the quotient is a whole number, then 3 and 5,857,718.3333 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 | 17,573,155 | |
| -1 | -17,573,155 |
Let's try dividing by 4:
17,573,155 ÷ 4 = 4,393,288.75
If the quotient is a whole number, then 4 and 4,393,288.75 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 | 17,573,155 | |
| -1 | 17,573,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 79 | 85 | 395 | 1,343 | 2,617 | 6,715 | 13,085 | 44,489 | 206,743 | 222,445 | 1,033,715 | 3,514,631 | 17,573,155 |
| -1 | -5 | -17 | -79 | -85 | -395 | -1,343 | -2,617 | -6,715 | -13,085 | -44,489 | -206,743 | -222,445 | -1,033,715 | -3,514,631 | -17,573,155 |
