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 23,490,245, 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 | 23,490,245 | |
| -1 | -23,490,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,490,245.
Example:
1 x 23,490,245 = 23,490,245
and
-1 x -23,490,245 = 23,490,245
Notice both answers equal 23,490,245
With that explanation out of the way, let's continue. Next, we take the number 23,490,245 and divide it by 2:
23,490,245 ÷ 2 = 11,745,122.5
If the quotient is a whole number, then 2 and 11,745,122.5 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 | 23,490,245 | |
| -1 | -23,490,245 |
Now, we try dividing 23,490,245 by 3:
23,490,245 ÷ 3 = 7,830,081.6667
If the quotient is a whole number, then 3 and 7,830,081.6667 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 | 23,490,245 | |
| -1 | -23,490,245 |
Let's try dividing by 4:
23,490,245 ÷ 4 = 5,872,561.25
If the quotient is a whole number, then 4 and 5,872,561.25 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 | 23,490,245 | |
| -1 | 23,490,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 83 | 107 | 115 | 415 | 529 | 535 | 1,909 | 2,461 | 2,645 | 8,881 | 9,545 | 12,305 | 43,907 | 44,405 | 56,603 | 204,263 | 219,535 | 283,015 | 1,021,315 | 4,698,049 | 23,490,245 |
| -1 | -5 | -23 | -83 | -107 | -115 | -415 | -529 | -535 | -1,909 | -2,461 | -2,645 | -8,881 | -9,545 | -12,305 | -43,907 | -44,405 | -56,603 | -204,263 | -219,535 | -283,015 | -1,021,315 | -4,698,049 | -23,490,245 |
