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 111,146,545, 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 | 111,146,545 | |
| -1 | -111,146,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,146,545.
Example:
1 x 111,146,545 = 111,146,545
and
-1 x -111,146,545 = 111,146,545
Notice both answers equal 111,146,545
With that explanation out of the way, let's continue. Next, we take the number 111,146,545 and divide it by 2:
111,146,545 ÷ 2 = 55,573,272.5
If the quotient is a whole number, then 2 and 55,573,272.5 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 | 111,146,545 | |
| -1 | -111,146,545 |
Now, we try dividing 111,146,545 by 3:
111,146,545 ÷ 3 = 37,048,848.3333
If the quotient is a whole number, then 3 and 37,048,848.3333 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 | 111,146,545 | |
| -1 | -111,146,545 |
Let's try dividing by 4:
111,146,545 ÷ 4 = 27,786,636.25
If the quotient is a whole number, then 4 and 27,786,636.25 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 | 111,146,545 | |
| -1 | 111,146,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 223 | 415 | 1,115 | 1,201 | 6,005 | 18,509 | 92,545 | 99,683 | 267,823 | 498,415 | 1,339,115 | 22,229,309 | 111,146,545 |
| -1 | -5 | -83 | -223 | -415 | -1,115 | -1,201 | -6,005 | -18,509 | -92,545 | -99,683 | -267,823 | -498,415 | -1,339,115 | -22,229,309 | -111,146,545 |
