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 111,061,271, 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 | 111,061,271 | |
| -1 | -111,061,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,061,271.
Example:
1 x 111,061,271 = 111,061,271
and
-1 x -111,061,271 = 111,061,271
Notice both answers equal 111,061,271
With that explanation out of the way, let's continue. Next, we take the number 111,061,271 and divide it by 2:
111,061,271 ÷ 2 = 55,530,635.5
If the quotient is a whole number, then 2 and 55,530,635.5 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 | 111,061,271 | |
| -1 | -111,061,271 |
Now, we try dividing 111,061,271 by 3:
111,061,271 ÷ 3 = 37,020,423.6667
If the quotient is a whole number, then 3 and 37,020,423.6667 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 | 111,061,271 | |
| -1 | -111,061,271 |
Let's try dividing by 4:
111,061,271 ÷ 4 = 27,765,317.75
If the quotient is a whole number, then 4 and 27,765,317.75 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 | 111,061,271 | |
| -1 | 111,061,271 |
If you did it right, you will end up with this table:
| 1 | 29 | 193 | 5,597 | 19,843 | 575,447 | 3,829,699 | 111,061,271 |
| -1 | -29 | -193 | -5,597 | -19,843 | -575,447 | -3,829,699 | -111,061,271 |
