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 23,042,905, 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 | 23,042,905 | |
| -1 | -23,042,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,042,905.
Example:
1 x 23,042,905 = 23,042,905
and
-1 x -23,042,905 = 23,042,905
Notice both answers equal 23,042,905
With that explanation out of the way, let's continue. Next, we take the number 23,042,905 and divide it by 2:
23,042,905 ÷ 2 = 11,521,452.5
If the quotient is a whole number, then 2 and 11,521,452.5 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 | 23,042,905 | |
| -1 | -23,042,905 |
Now, we try dividing 23,042,905 by 3:
23,042,905 ÷ 3 = 7,680,968.3333
If the quotient is a whole number, then 3 and 7,680,968.3333 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 | 23,042,905 | |
| -1 | -23,042,905 |
Let's try dividing by 4:
23,042,905 ÷ 4 = 5,760,726.25
If the quotient is a whole number, then 4 and 5,760,726.25 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 | 23,042,905 | |
| -1 | 23,042,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 419 | 647 | 2,095 | 3,235 | 7,123 | 10,999 | 35,615 | 54,995 | 271,093 | 1,355,465 | 4,608,581 | 23,042,905 |
| -1 | -5 | -17 | -85 | -419 | -647 | -2,095 | -3,235 | -7,123 | -10,999 | -35,615 | -54,995 | -271,093 | -1,355,465 | -4,608,581 | -23,042,905 |
