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 113,724,457, 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 | 113,724,457 | |
| -1 | -113,724,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,724,457.
Example:
1 x 113,724,457 = 113,724,457
and
-1 x -113,724,457 = 113,724,457
Notice both answers equal 113,724,457
With that explanation out of the way, let's continue. Next, we take the number 113,724,457 and divide it by 2:
113,724,457 ÷ 2 = 56,862,228.5
If the quotient is a whole number, then 2 and 56,862,228.5 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 | 113,724,457 | |
| -1 | -113,724,457 |
Now, we try dividing 113,724,457 by 3:
113,724,457 ÷ 3 = 37,908,152.3333
If the quotient is a whole number, then 3 and 37,908,152.3333 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 | 113,724,457 | |
| -1 | -113,724,457 |
Let's try dividing by 4:
113,724,457 ÷ 4 = 28,431,114.25
If the quotient is a whole number, then 4 and 28,431,114.25 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 | 113,724,457 | |
| -1 | 113,724,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 50,929 | 356,503 | 560,219 | 1,476,941 | 3,921,533 | 10,338,587 | 16,246,351 | 113,724,457 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -50,929 | -356,503 | -560,219 | -1,476,941 | -3,921,533 | -10,338,587 | -16,246,351 | -113,724,457 |
