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 110,668,145, 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 | 110,668,145 | |
| -1 | -110,668,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,668,145.
Example:
1 x 110,668,145 = 110,668,145
and
-1 x -110,668,145 = 110,668,145
Notice both answers equal 110,668,145
With that explanation out of the way, let's continue. Next, we take the number 110,668,145 and divide it by 2:
110,668,145 ÷ 2 = 55,334,072.5
If the quotient is a whole number, then 2 and 55,334,072.5 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 | 110,668,145 | |
| -1 | -110,668,145 |
Now, we try dividing 110,668,145 by 3:
110,668,145 ÷ 3 = 36,889,381.6667
If the quotient is a whole number, then 3 and 36,889,381.6667 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 | 110,668,145 | |
| -1 | -110,668,145 |
Let's try dividing by 4:
110,668,145 ÷ 4 = 27,667,036.25
If the quotient is a whole number, then 4 and 27,667,036.25 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 | 110,668,145 | |
| -1 | 110,668,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 131 | 655 | 917 | 4,585 | 24,137 | 120,685 | 168,959 | 844,795 | 3,161,947 | 15,809,735 | 22,133,629 | 110,668,145 |
| -1 | -5 | -7 | -35 | -131 | -655 | -917 | -4,585 | -24,137 | -120,685 | -168,959 | -844,795 | -3,161,947 | -15,809,735 | -22,133,629 | -110,668,145 |
