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 17,640,265, 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 | 17,640,265 | |
| -1 | -17,640,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,640,265.
Example:
1 x 17,640,265 = 17,640,265
and
-1 x -17,640,265 = 17,640,265
Notice both answers equal 17,640,265
With that explanation out of the way, let's continue. Next, we take the number 17,640,265 and divide it by 2:
17,640,265 ÷ 2 = 8,820,132.5
If the quotient is a whole number, then 2 and 8,820,132.5 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 | 17,640,265 | |
| -1 | -17,640,265 |
Now, we try dividing 17,640,265 by 3:
17,640,265 ÷ 3 = 5,880,088.3333
If the quotient is a whole number, then 3 and 5,880,088.3333 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 | 17,640,265 | |
| -1 | -17,640,265 |
Let's try dividing by 4:
17,640,265 ÷ 4 = 4,410,066.25
If the quotient is a whole number, then 4 and 4,410,066.25 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 | 17,640,265 | |
| -1 | 17,640,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 337 | 361 | 551 | 1,685 | 1,805 | 2,755 | 6,403 | 9,773 | 10,469 | 32,015 | 48,865 | 52,345 | 121,657 | 185,687 | 608,285 | 928,435 | 3,528,053 | 17,640,265 |
| -1 | -5 | -19 | -29 | -95 | -145 | -337 | -361 | -551 | -1,685 | -1,805 | -2,755 | -6,403 | -9,773 | -10,469 | -32,015 | -48,865 | -52,345 | -121,657 | -185,687 | -608,285 | -928,435 | -3,528,053 | -17,640,265 |
