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 17,982,475, 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 | 17,982,475 | |
| -1 | -17,982,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,982,475.
Example:
1 x 17,982,475 = 17,982,475
and
-1 x -17,982,475 = 17,982,475
Notice both answers equal 17,982,475
With that explanation out of the way, let's continue. Next, we take the number 17,982,475 and divide it by 2:
17,982,475 ÷ 2 = 8,991,237.5
If the quotient is a whole number, then 2 and 8,991,237.5 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 | 17,982,475 | |
| -1 | -17,982,475 |
Now, we try dividing 17,982,475 by 3:
17,982,475 ÷ 3 = 5,994,158.3333
If the quotient is a whole number, then 3 and 5,994,158.3333 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 | 17,982,475 | |
| -1 | -17,982,475 |
Let's try dividing by 4:
17,982,475 ÷ 4 = 4,495,618.75
If the quotient is a whole number, then 4 and 4,495,618.75 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 | 17,982,475 | |
| -1 | 17,982,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 211 | 487 | 1,055 | 1,477 | 2,435 | 3,409 | 5,275 | 7,385 | 12,175 | 17,045 | 36,925 | 85,225 | 102,757 | 513,785 | 719,299 | 2,568,925 | 3,596,495 | 17,982,475 |
| -1 | -5 | -7 | -25 | -35 | -175 | -211 | -487 | -1,055 | -1,477 | -2,435 | -3,409 | -5,275 | -7,385 | -12,175 | -17,045 | -36,925 | -85,225 | -102,757 | -513,785 | -719,299 | -2,568,925 | -3,596,495 | -17,982,475 |
