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 23,654,465, 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 | 23,654,465 | |
| -1 | -23,654,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,654,465.
Example:
1 x 23,654,465 = 23,654,465
and
-1 x -23,654,465 = 23,654,465
Notice both answers equal 23,654,465
With that explanation out of the way, let's continue. Next, we take the number 23,654,465 and divide it by 2:
23,654,465 ÷ 2 = 11,827,232.5
If the quotient is a whole number, then 2 and 11,827,232.5 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 | 23,654,465 | |
| -1 | -23,654,465 |
Now, we try dividing 23,654,465 by 3:
23,654,465 ÷ 3 = 7,884,821.6667
If the quotient is a whole number, then 3 and 7,884,821.6667 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 | 23,654,465 | |
| -1 | -23,654,465 |
Let's try dividing by 4:
23,654,465 ÷ 4 = 5,913,616.25
If the quotient is a whole number, then 4 and 5,913,616.25 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 | 23,654,465 | |
| -1 | 23,654,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 103 | 115 | 515 | 1,997 | 2,369 | 9,985 | 11,845 | 45,931 | 205,691 | 229,655 | 1,028,455 | 4,730,893 | 23,654,465 |
| -1 | -5 | -23 | -103 | -115 | -515 | -1,997 | -2,369 | -9,985 | -11,845 | -45,931 | -205,691 | -229,655 | -1,028,455 | -4,730,893 | -23,654,465 |
