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 110,202,421, 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 | 110,202,421 | |
| -1 | -110,202,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,202,421.
Example:
1 x 110,202,421 = 110,202,421
and
-1 x -110,202,421 = 110,202,421
Notice both answers equal 110,202,421
With that explanation out of the way, let's continue. Next, we take the number 110,202,421 and divide it by 2:
110,202,421 ÷ 2 = 55,101,210.5
If the quotient is a whole number, then 2 and 55,101,210.5 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 | 110,202,421 | |
| -1 | -110,202,421 |
Now, we try dividing 110,202,421 by 3:
110,202,421 ÷ 3 = 36,734,140.3333
If the quotient is a whole number, then 3 and 36,734,140.3333 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 | 110,202,421 | |
| -1 | -110,202,421 |
Let's try dividing by 4:
110,202,421 ÷ 4 = 27,550,605.25
If the quotient is a whole number, then 4 and 27,550,605.25 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 | 110,202,421 | |
| -1 | 110,202,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 193 | 271 | 301 | 1,351 | 1,897 | 2,107 | 8,299 | 9,457 | 11,653 | 13,279 | 52,303 | 58,093 | 81,571 | 366,121 | 406,651 | 570,997 | 2,249,029 | 2,562,847 | 15,743,203 | 110,202,421 |
| -1 | -7 | -43 | -49 | -193 | -271 | -301 | -1,351 | -1,897 | -2,107 | -8,299 | -9,457 | -11,653 | -13,279 | -52,303 | -58,093 | -81,571 | -366,121 | -406,651 | -570,997 | -2,249,029 | -2,562,847 | -15,743,203 | -110,202,421 |
