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 111,202,217, 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 | 111,202,217 | |
| -1 | -111,202,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,202,217.
Example:
1 x 111,202,217 = 111,202,217
and
-1 x -111,202,217 = 111,202,217
Notice both answers equal 111,202,217
With that explanation out of the way, let's continue. Next, we take the number 111,202,217 and divide it by 2:
111,202,217 ÷ 2 = 55,601,108.5
If the quotient is a whole number, then 2 and 55,601,108.5 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 | 111,202,217 | |
| -1 | -111,202,217 |
Now, we try dividing 111,202,217 by 3:
111,202,217 ÷ 3 = 37,067,405.6667
If the quotient is a whole number, then 3 and 37,067,405.6667 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 | 111,202,217 | |
| -1 | -111,202,217 |
Let's try dividing by 4:
111,202,217 ÷ 4 = 27,800,554.25
If the quotient is a whole number, then 4 and 27,800,554.25 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 | 111,202,217 | |
| -1 | 111,202,217 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 79 | 161 | 553 | 1,127 | 1,249 | 1,817 | 3,871 | 8,743 | 12,719 | 28,727 | 61,201 | 89,033 | 98,671 | 201,089 | 690,697 | 1,407,623 | 2,269,433 | 4,834,879 | 15,886,031 | 111,202,217 |
| -1 | -7 | -23 | -49 | -79 | -161 | -553 | -1,127 | -1,249 | -1,817 | -3,871 | -8,743 | -12,719 | -28,727 | -61,201 | -89,033 | -98,671 | -201,089 | -690,697 | -1,407,623 | -2,269,433 | -4,834,879 | -15,886,031 | -111,202,217 |
