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 224,000,405, 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 | 224,000,405 | |
| -1 | -224,000,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,000,405.
Example:
1 x 224,000,405 = 224,000,405
and
-1 x -224,000,405 = 224,000,405
Notice both answers equal 224,000,405
With that explanation out of the way, let's continue. Next, we take the number 224,000,405 and divide it by 2:
224,000,405 ÷ 2 = 112,000,202.5
If the quotient is a whole number, then 2 and 112,000,202.5 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 | 224,000,405 | |
| -1 | -224,000,405 |
Now, we try dividing 224,000,405 by 3:
224,000,405 ÷ 3 = 74,666,801.6667
If the quotient is a whole number, then 3 and 74,666,801.6667 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 | 224,000,405 | |
| -1 | -224,000,405 |
Let's try dividing by 4:
224,000,405 ÷ 4 = 56,000,101.25
If the quotient is a whole number, then 4 and 56,000,101.25 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 | 224,000,405 | |
| -1 | 224,000,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 63,727 | 318,635 | 1,210,813 | 2,357,899 | 6,054,065 | 11,789,495 | 44,800,081 | 224,000,405 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -63,727 | -318,635 | -1,210,813 | -2,357,899 | -6,054,065 | -11,789,495 | -44,800,081 | -224,000,405 |
