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 228,676,153, 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 | 228,676,153 | |
| -1 | -228,676,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,676,153.
Example:
1 x 228,676,153 = 228,676,153
and
-1 x -228,676,153 = 228,676,153
Notice both answers equal 228,676,153
With that explanation out of the way, let's continue. Next, we take the number 228,676,153 and divide it by 2:
228,676,153 ÷ 2 = 114,338,076.5
If the quotient is a whole number, then 2 and 114,338,076.5 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 | 228,676,153 | |
| -1 | -228,676,153 |
Now, we try dividing 228,676,153 by 3:
228,676,153 ÷ 3 = 76,225,384.3333
If the quotient is a whole number, then 3 and 76,225,384.3333 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 | 228,676,153 | |
| -1 | -228,676,153 |
Let's try dividing by 4:
228,676,153 ÷ 4 = 57,169,038.25
If the quotient is a whole number, then 4 and 57,169,038.25 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 | 228,676,153 | |
| -1 | 228,676,153 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 137 | 1,121 | 1,489 | 2,603 | 8,083 | 28,291 | 87,851 | 153,577 | 203,993 | 1,669,169 | 3,875,867 | 12,035,587 | 228,676,153 |
| -1 | -19 | -59 | -137 | -1,121 | -1,489 | -2,603 | -8,083 | -28,291 | -87,851 | -153,577 | -203,993 | -1,669,169 | -3,875,867 | -12,035,587 | -228,676,153 |
