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 228,654,625, 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 | 228,654,625 | |
| -1 | -228,654,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,654,625.
Example:
1 x 228,654,625 = 228,654,625
and
-1 x -228,654,625 = 228,654,625
Notice both answers equal 228,654,625
With that explanation out of the way, let's continue. Next, we take the number 228,654,625 and divide it by 2:
228,654,625 ÷ 2 = 114,327,312.5
If the quotient is a whole number, then 2 and 114,327,312.5 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 | 228,654,625 | |
| -1 | -228,654,625 |
Now, we try dividing 228,654,625 by 3:
228,654,625 ÷ 3 = 76,218,208.3333
If the quotient is a whole number, then 3 and 76,218,208.3333 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 | 228,654,625 | |
| -1 | -228,654,625 |
Let's try dividing by 4:
228,654,625 ÷ 4 = 57,163,656.25
If the quotient is a whole number, then 4 and 57,163,656.25 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 | 228,654,625 | |
| -1 | 228,654,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 125 | 415 | 2,075 | 10,375 | 22,039 | 110,195 | 550,975 | 1,829,237 | 2,754,875 | 9,146,185 | 45,730,925 | 228,654,625 |
| -1 | -5 | -25 | -83 | -125 | -415 | -2,075 | -10,375 | -22,039 | -110,195 | -550,975 | -1,829,237 | -2,754,875 | -9,146,185 | -45,730,925 | -228,654,625 |
