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 113,820,871, 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 | 113,820,871 | |
| -1 | -113,820,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,820,871.
Example:
1 x 113,820,871 = 113,820,871
and
-1 x -113,820,871 = 113,820,871
Notice both answers equal 113,820,871
With that explanation out of the way, let's continue. Next, we take the number 113,820,871 and divide it by 2:
113,820,871 ÷ 2 = 56,910,435.5
If the quotient is a whole number, then 2 and 56,910,435.5 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 | 113,820,871 | |
| -1 | -113,820,871 |
Now, we try dividing 113,820,871 by 3:
113,820,871 ÷ 3 = 37,940,290.3333
If the quotient is a whole number, then 3 and 37,940,290.3333 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 | 113,820,871 | |
| -1 | -113,820,871 |
Let's try dividing by 4:
113,820,871 ÷ 4 = 28,455,217.75
If the quotient is a whole number, then 4 and 28,455,217.75 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 | 113,820,871 | |
| -1 | 113,820,871 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 103 | 829 | 1,333 | 3,193 | 4,429 | 25,699 | 35,647 | 85,387 | 137,299 | 1,105,057 | 2,646,997 | 3,671,641 | 113,820,871 |
| -1 | -31 | -43 | -103 | -829 | -1,333 | -3,193 | -4,429 | -25,699 | -35,647 | -85,387 | -137,299 | -1,105,057 | -2,646,997 | -3,671,641 | -113,820,871 |
