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 113,312,219, 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 | 113,312,219 | |
| -1 | -113,312,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,312,219.
Example:
1 x 113,312,219 = 113,312,219
and
-1 x -113,312,219 = 113,312,219
Notice both answers equal 113,312,219
With that explanation out of the way, let's continue. Next, we take the number 113,312,219 and divide it by 2:
113,312,219 ÷ 2 = 56,656,109.5
If the quotient is a whole number, then 2 and 56,656,109.5 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 | 113,312,219 | |
| -1 | -113,312,219 |
Now, we try dividing 113,312,219 by 3:
113,312,219 ÷ 3 = 37,770,739.6667
If the quotient is a whole number, then 3 and 37,770,739.6667 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 | 113,312,219 | |
| -1 | -113,312,219 |
Let's try dividing by 4:
113,312,219 ÷ 4 = 28,328,054.75
If the quotient is a whole number, then 4 and 28,328,054.75 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 | 113,312,219 | |
| -1 | 113,312,219 |
If you did it right, you will end up with this table:
| 1 | 19 | 89 | 113 | 593 | 1,691 | 2,147 | 10,057 | 11,267 | 52,777 | 67,009 | 191,083 | 1,002,763 | 1,273,171 | 5,963,801 | 113,312,219 |
| -1 | -19 | -89 | -113 | -593 | -1,691 | -2,147 | -10,057 | -11,267 | -52,777 | -67,009 | -191,083 | -1,002,763 | -1,273,171 | -5,963,801 | -113,312,219 |
