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 224,321,455, 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 | 224,321,455 | |
| -1 | -224,321,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,321,455.
Example:
1 x 224,321,455 = 224,321,455
and
-1 x -224,321,455 = 224,321,455
Notice both answers equal 224,321,455
With that explanation out of the way, let's continue. Next, we take the number 224,321,455 and divide it by 2:
224,321,455 ÷ 2 = 112,160,727.5
If the quotient is a whole number, then 2 and 112,160,727.5 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 | 224,321,455 | |
| -1 | -224,321,455 |
Now, we try dividing 224,321,455 by 3:
224,321,455 ÷ 3 = 74,773,818.3333
If the quotient is a whole number, then 3 and 74,773,818.3333 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 | 224,321,455 | |
| -1 | -224,321,455 |
Let's try dividing by 4:
224,321,455 ÷ 4 = 56,080,363.75
If the quotient is a whole number, then 4 and 56,080,363.75 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 | 224,321,455 | |
| -1 | 224,321,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 109 | 205 | 545 | 4,469 | 10,039 | 22,345 | 50,195 | 411,599 | 1,094,251 | 2,057,995 | 5,471,255 | 44,864,291 | 224,321,455 |
| -1 | -5 | -41 | -109 | -205 | -545 | -4,469 | -10,039 | -22,345 | -50,195 | -411,599 | -1,094,251 | -2,057,995 | -5,471,255 | -44,864,291 | -224,321,455 |
