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 23,422,345, 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 | 23,422,345 | |
| -1 | -23,422,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,422,345.
Example:
1 x 23,422,345 = 23,422,345
and
-1 x -23,422,345 = 23,422,345
Notice both answers equal 23,422,345
With that explanation out of the way, let's continue. Next, we take the number 23,422,345 and divide it by 2:
23,422,345 ÷ 2 = 11,711,172.5
If the quotient is a whole number, then 2 and 11,711,172.5 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 | 23,422,345 | |
| -1 | -23,422,345 |
Now, we try dividing 23,422,345 by 3:
23,422,345 ÷ 3 = 7,807,448.3333
If the quotient is a whole number, then 3 and 7,807,448.3333 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 | 23,422,345 | |
| -1 | -23,422,345 |
Let's try dividing by 4:
23,422,345 ÷ 4 = 5,855,586.25
If the quotient is a whole number, then 4 and 5,855,586.25 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 | 23,422,345 | |
| -1 | 23,422,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 14,503 | 72,515 | 246,551 | 275,557 | 1,232,755 | 1,377,785 | 4,684,469 | 23,422,345 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -14,503 | -72,515 | -246,551 | -275,557 | -1,232,755 | -1,377,785 | -4,684,469 | -23,422,345 |
