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 23,315,347, 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 | 23,315,347 | |
| -1 | -23,315,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,315,347.
Example:
1 x 23,315,347 = 23,315,347
and
-1 x -23,315,347 = 23,315,347
Notice both answers equal 23,315,347
With that explanation out of the way, let's continue. Next, we take the number 23,315,347 and divide it by 2:
23,315,347 ÷ 2 = 11,657,673.5
If the quotient is a whole number, then 2 and 11,657,673.5 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 | 23,315,347 | |
| -1 | -23,315,347 |
Now, we try dividing 23,315,347 by 3:
23,315,347 ÷ 3 = 7,771,782.3333
If the quotient is a whole number, then 3 and 7,771,782.3333 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 | 23,315,347 | |
| -1 | -23,315,347 |
Let's try dividing by 4:
23,315,347 ÷ 4 = 5,828,836.75
If the quotient is a whole number, then 4 and 5,828,836.75 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 | 23,315,347 | |
| -1 | 23,315,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 451 | 697 | 3,041 | 7,667 | 33,451 | 51,697 | 124,681 | 568,667 | 1,371,491 | 2,119,577 | 23,315,347 |
| -1 | -11 | -17 | -41 | -187 | -451 | -697 | -3,041 | -7,667 | -33,451 | -51,697 | -124,681 | -568,667 | -1,371,491 | -2,119,577 | -23,315,347 |
