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 111,161,701, 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 | 111,161,701 | |
| -1 | -111,161,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,161,701.
Example:
1 x 111,161,701 = 111,161,701
and
-1 x -111,161,701 = 111,161,701
Notice both answers equal 111,161,701
With that explanation out of the way, let's continue. Next, we take the number 111,161,701 and divide it by 2:
111,161,701 ÷ 2 = 55,580,850.5
If the quotient is a whole number, then 2 and 55,580,850.5 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 | 111,161,701 | |
| -1 | -111,161,701 |
Now, we try dividing 111,161,701 by 3:
111,161,701 ÷ 3 = 37,053,900.3333
If the quotient is a whole number, then 3 and 37,053,900.3333 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 | 111,161,701 | |
| -1 | -111,161,701 |
Let's try dividing by 4:
111,161,701 ÷ 4 = 27,790,425.25
If the quotient is a whole number, then 4 and 27,790,425.25 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 | 111,161,701 | |
| -1 | 111,161,701 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 409 | 947 | 2,863 | 6,629 | 16,769 | 38,827 | 117,383 | 271,789 | 387,323 | 2,711,261 | 15,880,243 | 111,161,701 |
| -1 | -7 | -41 | -287 | -409 | -947 | -2,863 | -6,629 | -16,769 | -38,827 | -117,383 | -271,789 | -387,323 | -2,711,261 | -15,880,243 | -111,161,701 |
