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 228,475, 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 | 228,475 | |
| -1 | -228,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,475.
Example:
1 x 228,475 = 228,475
and
-1 x -228,475 = 228,475
Notice both answers equal 228,475
With that explanation out of the way, let's continue. Next, we take the number 228,475 and divide it by 2:
228,475 ÷ 2 = 114,237.5
If the quotient is a whole number, then 2 and 114,237.5 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 | 228,475 | |
| -1 | -228,475 |
Now, we try dividing 228,475 by 3:
228,475 ÷ 3 = 76,158.3333
If the quotient is a whole number, then 3 and 76,158.3333 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 | 228,475 | |
| -1 | -228,475 |
Let's try dividing by 4:
228,475 ÷ 4 = 57,118.75
If the quotient is a whole number, then 4 and 57,118.75 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 | 228,475 | |
| -1 | 228,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 25 | 37 | 65 | 95 | 185 | 247 | 325 | 475 | 481 | 703 | 925 | 1,235 | 2,405 | 3,515 | 6,175 | 9,139 | 12,025 | 17,575 | 45,695 | 228,475 |
| -1 | -5 | -13 | -19 | -25 | -37 | -65 | -95 | -185 | -247 | -325 | -475 | -481 | -703 | -925 | -1,235 | -2,405 | -3,515 | -6,175 | -9,139 | -12,025 | -17,575 | -45,695 | -228,475 |
