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 23,177,099, 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 | 23,177,099 | |
| -1 | -23,177,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,177,099.
Example:
1 x 23,177,099 = 23,177,099
and
-1 x -23,177,099 = 23,177,099
Notice both answers equal 23,177,099
With that explanation out of the way, let's continue. Next, we take the number 23,177,099 and divide it by 2:
23,177,099 ÷ 2 = 11,588,549.5
If the quotient is a whole number, then 2 and 11,588,549.5 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 | 23,177,099 | |
| -1 | -23,177,099 |
Now, we try dividing 23,177,099 by 3:
23,177,099 ÷ 3 = 7,725,699.6667
If the quotient is a whole number, then 3 and 7,725,699.6667 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 | 23,177,099 | |
| -1 | -23,177,099 |
Let's try dividing by 4:
23,177,099 ÷ 4 = 5,794,274.75
If the quotient is a whole number, then 4 and 5,794,274.75 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 | 23,177,099 | |
| -1 | 23,177,099 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 149 | 179 | 869 | 1,639 | 1,969 | 11,771 | 14,141 | 26,671 | 129,481 | 155,551 | 293,381 | 2,107,009 | 23,177,099 |
| -1 | -11 | -79 | -149 | -179 | -869 | -1,639 | -1,969 | -11,771 | -14,141 | -26,671 | -129,481 | -155,551 | -293,381 | -2,107,009 | -23,177,099 |
