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 23,010,281, 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 | 23,010,281 | |
| -1 | -23,010,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,010,281.
Example:
1 x 23,010,281 = 23,010,281
and
-1 x -23,010,281 = 23,010,281
Notice both answers equal 23,010,281
With that explanation out of the way, let's continue. Next, we take the number 23,010,281 and divide it by 2:
23,010,281 ÷ 2 = 11,505,140.5
If the quotient is a whole number, then 2 and 11,505,140.5 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 | 23,010,281 | |
| -1 | -23,010,281 |
Now, we try dividing 23,010,281 by 3:
23,010,281 ÷ 3 = 7,670,093.6667
If the quotient is a whole number, then 3 and 7,670,093.6667 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 | 23,010,281 | |
| -1 | -23,010,281 |
Let's try dividing by 4:
23,010,281 ÷ 4 = 5,752,570.25
If the quotient is a whole number, then 4 and 5,752,570.25 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 | 23,010,281 | |
| -1 | 23,010,281 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 131 | 161 | 917 | 1,091 | 3,013 | 7,637 | 21,091 | 25,093 | 142,921 | 175,651 | 1,000,447 | 3,287,183 | 23,010,281 |
| -1 | -7 | -23 | -131 | -161 | -917 | -1,091 | -3,013 | -7,637 | -21,091 | -25,093 | -142,921 | -175,651 | -1,000,447 | -3,287,183 | -23,010,281 |
