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 23,456,719, 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 | 23,456,719 | |
| -1 | -23,456,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,456,719.
Example:
1 x 23,456,719 = 23,456,719
and
-1 x -23,456,719 = 23,456,719
Notice both answers equal 23,456,719
With that explanation out of the way, let's continue. Next, we take the number 23,456,719 and divide it by 2:
23,456,719 ÷ 2 = 11,728,359.5
If the quotient is a whole number, then 2 and 11,728,359.5 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 | 23,456,719 | |
| -1 | -23,456,719 |
Now, we try dividing 23,456,719 by 3:
23,456,719 ÷ 3 = 7,818,906.3333
If the quotient is a whole number, then 3 and 7,818,906.3333 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 | 23,456,719 | |
| -1 | -23,456,719 |
Let's try dividing by 4:
23,456,719 ÷ 4 = 5,864,179.75
If the quotient is a whole number, then 4 and 5,864,179.75 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 | 23,456,719 | |
| -1 | 23,456,719 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 2,431 | 9,649 | 106,139 | 125,437 | 164,033 | 1,379,807 | 1,804,363 | 2,132,429 | 23,456,719 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -2,431 | -9,649 | -106,139 | -125,437 | -164,033 | -1,379,807 | -1,804,363 | -2,132,429 | -23,456,719 |
