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 23,530,351, 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 | 23,530,351 | |
| -1 | -23,530,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,530,351.
Example:
1 x 23,530,351 = 23,530,351
and
-1 x -23,530,351 = 23,530,351
Notice both answers equal 23,530,351
With that explanation out of the way, let's continue. Next, we take the number 23,530,351 and divide it by 2:
23,530,351 ÷ 2 = 11,765,175.5
If the quotient is a whole number, then 2 and 11,765,175.5 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 | 23,530,351 | |
| -1 | -23,530,351 |
Now, we try dividing 23,530,351 by 3:
23,530,351 ÷ 3 = 7,843,450.3333
If the quotient is a whole number, then 3 and 7,843,450.3333 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 | 23,530,351 | |
| -1 | -23,530,351 |
Let's try dividing by 4:
23,530,351 ÷ 4 = 5,882,587.75
If the quotient is a whole number, then 4 and 5,882,587.75 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 | 23,530,351 | |
| -1 | 23,530,351 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 131 | 337 | 533 | 1,703 | 4,381 | 5,371 | 13,817 | 44,147 | 69,823 | 179,621 | 573,911 | 1,810,027 | 23,530,351 |
| -1 | -13 | -41 | -131 | -337 | -533 | -1,703 | -4,381 | -5,371 | -13,817 | -44,147 | -69,823 | -179,621 | -573,911 | -1,810,027 | -23,530,351 |
