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 17,445,715, 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 | 17,445,715 | |
| -1 | -17,445,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,445,715.
Example:
1 x 17,445,715 = 17,445,715
and
-1 x -17,445,715 = 17,445,715
Notice both answers equal 17,445,715
With that explanation out of the way, let's continue. Next, we take the number 17,445,715 and divide it by 2:
17,445,715 ÷ 2 = 8,722,857.5
If the quotient is a whole number, then 2 and 8,722,857.5 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 | 17,445,715 | |
| -1 | -17,445,715 |
Now, we try dividing 17,445,715 by 3:
17,445,715 ÷ 3 = 5,815,238.3333
If the quotient is a whole number, then 3 and 5,815,238.3333 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 | 17,445,715 | |
| -1 | -17,445,715 |
Let's try dividing by 4:
17,445,715 ÷ 4 = 4,361,428.75
If the quotient is a whole number, then 4 and 4,361,428.75 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 | 17,445,715 | |
| -1 | 17,445,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 155 | 217 | 245 | 1,085 | 1,519 | 2,297 | 7,595 | 11,485 | 16,079 | 71,207 | 80,395 | 112,553 | 356,035 | 498,449 | 562,765 | 2,492,245 | 3,489,143 | 17,445,715 |
| -1 | -5 | -7 | -31 | -35 | -49 | -155 | -217 | -245 | -1,085 | -1,519 | -2,297 | -7,595 | -11,485 | -16,079 | -71,207 | -80,395 | -112,553 | -356,035 | -498,449 | -562,765 | -2,492,245 | -3,489,143 | -17,445,715 |
