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 224,402,321, 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 | 224,402,321 | |
| -1 | -224,402,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,402,321.
Example:
1 x 224,402,321 = 224,402,321
and
-1 x -224,402,321 = 224,402,321
Notice both answers equal 224,402,321
With that explanation out of the way, let's continue. Next, we take the number 224,402,321 and divide it by 2:
224,402,321 ÷ 2 = 112,201,160.5
If the quotient is a whole number, then 2 and 112,201,160.5 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 | 224,402,321 | |
| -1 | -224,402,321 |
Now, we try dividing 224,402,321 by 3:
224,402,321 ÷ 3 = 74,800,773.6667
If the quotient is a whole number, then 3 and 74,800,773.6667 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 | 224,402,321 | |
| -1 | -224,402,321 |
Let's try dividing by 4:
224,402,321 ÷ 4 = 56,100,580.25
If the quotient is a whole number, then 4 and 56,100,580.25 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 | 224,402,321 | |
| -1 | 224,402,321 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 509 | 3,083 | 5,599 | 6,617 | 33,913 | 40,079 | 72,787 | 440,869 | 1,569,247 | 17,261,717 | 20,400,211 | 224,402,321 |
| -1 | -11 | -13 | -143 | -509 | -3,083 | -5,599 | -6,617 | -33,913 | -40,079 | -72,787 | -440,869 | -1,569,247 | -17,261,717 | -20,400,211 | -224,402,321 |
