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 23,671,165, 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 | 23,671,165 | |
| -1 | -23,671,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,671,165.
Example:
1 x 23,671,165 = 23,671,165
and
-1 x -23,671,165 = 23,671,165
Notice both answers equal 23,671,165
With that explanation out of the way, let's continue. Next, we take the number 23,671,165 and divide it by 2:
23,671,165 ÷ 2 = 11,835,582.5
If the quotient is a whole number, then 2 and 11,835,582.5 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 | 23,671,165 | |
| -1 | -23,671,165 |
Now, we try dividing 23,671,165 by 3:
23,671,165 ÷ 3 = 7,890,388.3333
If the quotient is a whole number, then 3 and 7,890,388.3333 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 | 23,671,165 | |
| -1 | -23,671,165 |
Let's try dividing by 4:
23,671,165 ÷ 4 = 5,917,791.25
If the quotient is a whole number, then 4 and 5,917,791.25 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 | 23,671,165 | |
| -1 | 23,671,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 79 | 245 | 395 | 553 | 1,223 | 2,765 | 3,871 | 6,115 | 8,561 | 19,355 | 42,805 | 59,927 | 96,617 | 299,635 | 483,085 | 676,319 | 3,381,595 | 4,734,233 | 23,671,165 |
| -1 | -5 | -7 | -35 | -49 | -79 | -245 | -395 | -553 | -1,223 | -2,765 | -3,871 | -6,115 | -8,561 | -19,355 | -42,805 | -59,927 | -96,617 | -299,635 | -483,085 | -676,319 | -3,381,595 | -4,734,233 | -23,671,165 |
