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 23,654,155, 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 | 23,654,155 | |
| -1 | -23,654,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,654,155.
Example:
1 x 23,654,155 = 23,654,155
and
-1 x -23,654,155 = 23,654,155
Notice both answers equal 23,654,155
With that explanation out of the way, let's continue. Next, we take the number 23,654,155 and divide it by 2:
23,654,155 ÷ 2 = 11,827,077.5
If the quotient is a whole number, then 2 and 11,827,077.5 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 | 23,654,155 | |
| -1 | -23,654,155 |
Now, we try dividing 23,654,155 by 3:
23,654,155 ÷ 3 = 7,884,718.3333
If the quotient is a whole number, then 3 and 7,884,718.3333 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 | 23,654,155 | |
| -1 | -23,654,155 |
Let's try dividing by 4:
23,654,155 ÷ 4 = 5,913,538.75
If the quotient is a whole number, then 4 and 5,913,538.75 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 | 23,654,155 | |
| -1 | 23,654,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 1,055 | 1,477 | 3,203 | 7,385 | 16,015 | 22,421 | 112,105 | 675,833 | 3,379,165 | 4,730,831 | 23,654,155 |
| -1 | -5 | -7 | -35 | -211 | -1,055 | -1,477 | -3,203 | -7,385 | -16,015 | -22,421 | -112,105 | -675,833 | -3,379,165 | -4,730,831 | -23,654,155 |
