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 230,113,555, 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 | 230,113,555 | |
| -1 | -230,113,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,113,555.
Example:
1 x 230,113,555 = 230,113,555
and
-1 x -230,113,555 = 230,113,555
Notice both answers equal 230,113,555
With that explanation out of the way, let's continue. Next, we take the number 230,113,555 and divide it by 2:
230,113,555 ÷ 2 = 115,056,777.5
If the quotient is a whole number, then 2 and 115,056,777.5 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 | 230,113,555 | |
| -1 | -230,113,555 |
Now, we try dividing 230,113,555 by 3:
230,113,555 ÷ 3 = 76,704,518.3333
If the quotient is a whole number, then 3 and 76,704,518.3333 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 | 230,113,555 | |
| -1 | -230,113,555 |
Let's try dividing by 4:
230,113,555 ÷ 4 = 57,528,388.75
If the quotient is a whole number, then 4 and 57,528,388.75 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 | 230,113,555 | |
| -1 | 230,113,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 134,177 | 670,885 | 939,239 | 4,696,195 | 6,574,673 | 32,873,365 | 46,022,711 | 230,113,555 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -134,177 | -670,885 | -939,239 | -4,696,195 | -6,574,673 | -32,873,365 | -46,022,711 | -230,113,555 |
