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 224,220,353, 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 | 224,220,353 | |
| -1 | -224,220,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,220,353.
Example:
1 x 224,220,353 = 224,220,353
and
-1 x -224,220,353 = 224,220,353
Notice both answers equal 224,220,353
With that explanation out of the way, let's continue. Next, we take the number 224,220,353 and divide it by 2:
224,220,353 ÷ 2 = 112,110,176.5
If the quotient is a whole number, then 2 and 112,110,176.5 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 | 224,220,353 | |
| -1 | -224,220,353 |
Now, we try dividing 224,220,353 by 3:
224,220,353 ÷ 3 = 74,740,117.6667
If the quotient is a whole number, then 3 and 74,740,117.6667 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 | 224,220,353 | |
| -1 | -224,220,353 |
Let's try dividing by 4:
224,220,353 ÷ 4 = 56,055,088.25
If the quotient is a whole number, then 4 and 56,055,088.25 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 | 224,220,353 | |
| -1 | 224,220,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 151 | 161 | 401 | 529 | 1,057 | 2,807 | 3,473 | 3,703 | 9,223 | 24,311 | 60,551 | 64,561 | 79,879 | 212,129 | 423,857 | 559,153 | 1,392,673 | 1,484,903 | 9,748,711 | 32,031,479 | 224,220,353 |
| -1 | -7 | -23 | -151 | -161 | -401 | -529 | -1,057 | -2,807 | -3,473 | -3,703 | -9,223 | -24,311 | -60,551 | -64,561 | -79,879 | -212,129 | -423,857 | -559,153 | -1,392,673 | -1,484,903 | -9,748,711 | -32,031,479 | -224,220,353 |
