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 23,708,503, 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 | 23,708,503 | |
| -1 | -23,708,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,708,503.
Example:
1 x 23,708,503 = 23,708,503
and
-1 x -23,708,503 = 23,708,503
Notice both answers equal 23,708,503
With that explanation out of the way, let's continue. Next, we take the number 23,708,503 and divide it by 2:
23,708,503 ÷ 2 = 11,854,251.5
If the quotient is a whole number, then 2 and 11,854,251.5 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 | 23,708,503 | |
| -1 | -23,708,503 |
Now, we try dividing 23,708,503 by 3:
23,708,503 ÷ 3 = 7,902,834.3333
If the quotient is a whole number, then 3 and 7,902,834.3333 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 | 23,708,503 | |
| -1 | -23,708,503 |
Let's try dividing by 4:
23,708,503 ÷ 4 = 5,927,125.75
If the quotient is a whole number, then 4 and 5,927,125.75 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 | 23,708,503 | |
| -1 | 23,708,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 343 | 409 | 637 | 1,183 | 2,863 | 4,459 | 5,317 | 8,281 | 20,041 | 37,219 | 57,967 | 69,121 | 140,287 | 260,533 | 483,847 | 1,823,731 | 3,386,929 | 23,708,503 |
| -1 | -7 | -13 | -49 | -91 | -169 | -343 | -409 | -637 | -1,183 | -2,863 | -4,459 | -5,317 | -8,281 | -20,041 | -37,219 | -57,967 | -69,121 | -140,287 | -260,533 | -483,847 | -1,823,731 | -3,386,929 | -23,708,503 |
