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 23,010,143, 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 | 23,010,143 | |
| -1 | -23,010,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,010,143.
Example:
1 x 23,010,143 = 23,010,143
and
-1 x -23,010,143 = 23,010,143
Notice both answers equal 23,010,143
With that explanation out of the way, let's continue. Next, we take the number 23,010,143 and divide it by 2:
23,010,143 ÷ 2 = 11,505,071.5
If the quotient is a whole number, then 2 and 11,505,071.5 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 | 23,010,143 | |
| -1 | -23,010,143 |
Now, we try dividing 23,010,143 by 3:
23,010,143 ÷ 3 = 7,670,047.6667
If the quotient is a whole number, then 3 and 7,670,047.6667 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 | 23,010,143 | |
| -1 | -23,010,143 |
Let's try dividing by 4:
23,010,143 ÷ 4 = 5,752,535.75
If the quotient is a whole number, then 4 and 5,752,535.75 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 | 23,010,143 | |
| -1 | 23,010,143 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 41 | 299 | 533 | 943 | 1,877 | 12,259 | 24,401 | 43,171 | 76,957 | 561,223 | 1,000,441 | 1,770,011 | 23,010,143 |
| -1 | -13 | -23 | -41 | -299 | -533 | -943 | -1,877 | -12,259 | -24,401 | -43,171 | -76,957 | -561,223 | -1,000,441 | -1,770,011 | -23,010,143 |
