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 110,401,145, 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 | 110,401,145 | |
| -1 | -110,401,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,401,145.
Example:
1 x 110,401,145 = 110,401,145
and
-1 x -110,401,145 = 110,401,145
Notice both answers equal 110,401,145
With that explanation out of the way, let's continue. Next, we take the number 110,401,145 and divide it by 2:
110,401,145 ÷ 2 = 55,200,572.5
If the quotient is a whole number, then 2 and 55,200,572.5 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 | 110,401,145 | |
| -1 | -110,401,145 |
Now, we try dividing 110,401,145 by 3:
110,401,145 ÷ 3 = 36,800,381.6667
If the quotient is a whole number, then 3 and 36,800,381.6667 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 | 110,401,145 | |
| -1 | -110,401,145 |
Let's try dividing by 4:
110,401,145 ÷ 4 = 27,600,286.25
If the quotient is a whole number, then 4 and 27,600,286.25 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 | 110,401,145 | |
| -1 | 110,401,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 877 | 1,481 | 4,385 | 7,405 | 14,909 | 25,177 | 74,545 | 125,885 | 1,298,837 | 6,494,185 | 22,080,229 | 110,401,145 |
| -1 | -5 | -17 | -85 | -877 | -1,481 | -4,385 | -7,405 | -14,909 | -25,177 | -74,545 | -125,885 | -1,298,837 | -6,494,185 | -22,080,229 | -110,401,145 |
