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 230,151,355, 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 | 230,151,355 | |
| -1 | -230,151,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,151,355.
Example:
1 x 230,151,355 = 230,151,355
and
-1 x -230,151,355 = 230,151,355
Notice both answers equal 230,151,355
With that explanation out of the way, let's continue. Next, we take the number 230,151,355 and divide it by 2:
230,151,355 ÷ 2 = 115,075,677.5
If the quotient is a whole number, then 2 and 115,075,677.5 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 | 230,151,355 | |
| -1 | -230,151,355 |
Now, we try dividing 230,151,355 by 3:
230,151,355 ÷ 3 = 76,717,118.3333
If the quotient is a whole number, then 3 and 76,717,118.3333 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 | 230,151,355 | |
| -1 | -230,151,355 |
Let's try dividing by 4:
230,151,355 ÷ 4 = 57,537,838.75
If the quotient is a whole number, then 4 and 57,537,838.75 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 | 230,151,355 | |
| -1 | 230,151,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 386,809 | 1,934,045 | 2,707,663 | 6,575,753 | 13,538,315 | 32,878,765 | 46,030,271 | 230,151,355 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -386,809 | -1,934,045 | -2,707,663 | -6,575,753 | -13,538,315 | -32,878,765 | -46,030,271 | -230,151,355 |
