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 230,022,037, 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 | 230,022,037 | |
| -1 | -230,022,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,022,037.
Example:
1 x 230,022,037 = 230,022,037
and
-1 x -230,022,037 = 230,022,037
Notice both answers equal 230,022,037
With that explanation out of the way, let's continue. Next, we take the number 230,022,037 and divide it by 2:
230,022,037 ÷ 2 = 115,011,018.5
If the quotient is a whole number, then 2 and 115,011,018.5 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 | 230,022,037 | |
| -1 | -230,022,037 |
Now, we try dividing 230,022,037 by 3:
230,022,037 ÷ 3 = 76,674,012.3333
If the quotient is a whole number, then 3 and 76,674,012.3333 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 | 230,022,037 | |
| -1 | -230,022,037 |
Let's try dividing by 4:
230,022,037 ÷ 4 = 57,505,509.25
If the quotient is a whole number, then 4 and 57,505,509.25 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 | 230,022,037 | |
| -1 | 230,022,037 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 71 | 133 | 497 | 1,349 | 9,443 | 24,359 | 170,513 | 462,821 | 1,729,489 | 3,239,747 | 12,106,423 | 32,860,291 | 230,022,037 |
| -1 | -7 | -19 | -71 | -133 | -497 | -1,349 | -9,443 | -24,359 | -170,513 | -462,821 | -1,729,489 | -3,239,747 | -12,106,423 | -32,860,291 | -230,022,037 |
