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 223,264,249, 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 | 223,264,249 | |
| -1 | -223,264,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,264,249.
Example:
1 x 223,264,249 = 223,264,249
and
-1 x -223,264,249 = 223,264,249
Notice both answers equal 223,264,249
With that explanation out of the way, let's continue. Next, we take the number 223,264,249 and divide it by 2:
223,264,249 ÷ 2 = 111,632,124.5
If the quotient is a whole number, then 2 and 111,632,124.5 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 | 223,264,249 | |
| -1 | -223,264,249 |
Now, we try dividing 223,264,249 by 3:
223,264,249 ÷ 3 = 74,421,416.3333
If the quotient is a whole number, then 3 and 74,421,416.3333 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 | 223,264,249 | |
| -1 | -223,264,249 |
Let's try dividing by 4:
223,264,249 ÷ 4 = 55,816,062.25
If the quotient is a whole number, then 4 and 55,816,062.25 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 | 223,264,249 | |
| -1 | 223,264,249 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 251 | 689 | 1,291 | 3,263 | 13,303 | 16,783 | 68,423 | 172,939 | 324,041 | 889,499 | 4,212,533 | 17,174,173 | 223,264,249 |
| -1 | -13 | -53 | -251 | -689 | -1,291 | -3,263 | -13,303 | -16,783 | -68,423 | -172,939 | -324,041 | -889,499 | -4,212,533 | -17,174,173 | -223,264,249 |
