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 23,045,407, 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 | 23,045,407 | |
| -1 | -23,045,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,045,407.
Example:
1 x 23,045,407 = 23,045,407
and
-1 x -23,045,407 = 23,045,407
Notice both answers equal 23,045,407
With that explanation out of the way, let's continue. Next, we take the number 23,045,407 and divide it by 2:
23,045,407 ÷ 2 = 11,522,703.5
If the quotient is a whole number, then 2 and 11,522,703.5 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 | 23,045,407 | |
| -1 | -23,045,407 |
Now, we try dividing 23,045,407 by 3:
23,045,407 ÷ 3 = 7,681,802.3333
If the quotient is a whole number, then 3 and 7,681,802.3333 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 | 23,045,407 | |
| -1 | -23,045,407 |
Let's try dividing by 4:
23,045,407 ÷ 4 = 5,761,351.75
If the quotient is a whole number, then 4 and 5,761,351.75 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 | 23,045,407 | |
| -1 | 23,045,407 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 371 | 583 | 4,081 | 5,647 | 39,529 | 62,117 | 299,291 | 434,819 | 2,095,037 | 3,292,201 | 23,045,407 |
| -1 | -7 | -11 | -53 | -77 | -371 | -583 | -4,081 | -5,647 | -39,529 | -62,117 | -299,291 | -434,819 | -2,095,037 | -3,292,201 | -23,045,407 |
