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 113,422,211, 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 | 113,422,211 | |
| -1 | -113,422,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,422,211.
Example:
1 x 113,422,211 = 113,422,211
and
-1 x -113,422,211 = 113,422,211
Notice both answers equal 113,422,211
With that explanation out of the way, let's continue. Next, we take the number 113,422,211 and divide it by 2:
113,422,211 ÷ 2 = 56,711,105.5
If the quotient is a whole number, then 2 and 56,711,105.5 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 | 113,422,211 | |
| -1 | -113,422,211 |
Now, we try dividing 113,422,211 by 3:
113,422,211 ÷ 3 = 37,807,403.6667
If the quotient is a whole number, then 3 and 37,807,403.6667 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 | 113,422,211 | |
| -1 | -113,422,211 |
Let's try dividing by 4:
113,422,211 ÷ 4 = 28,355,552.75
If the quotient is a whole number, then 4 and 28,355,552.75 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 | 113,422,211 | |
| -1 | 113,422,211 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 217 | 343 | 1,519 | 10,633 | 10,667 | 74,669 | 330,677 | 522,683 | 2,314,739 | 3,658,781 | 16,203,173 | 113,422,211 |
| -1 | -7 | -31 | -49 | -217 | -343 | -1,519 | -10,633 | -10,667 | -74,669 | -330,677 | -522,683 | -2,314,739 | -3,658,781 | -16,203,173 | -113,422,211 |
