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 376,388,233, 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 | 376,388,233 | |
| -1 | -376,388,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 376,388,233.
Example:
1 x 376,388,233 = 376,388,233
and
-1 x -376,388,233 = 376,388,233
Notice both answers equal 376,388,233
With that explanation out of the way, let's continue. Next, we take the number 376,388,233 and divide it by 2:
376,388,233 ÷ 2 = 188,194,116.5
If the quotient is a whole number, then 2 and 188,194,116.5 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 | 376,388,233 | |
| -1 | -376,388,233 |
Now, we try dividing 376,388,233 by 3:
376,388,233 ÷ 3 = 125,462,744.3333
If the quotient is a whole number, then 3 and 125,462,744.3333 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 | 376,388,233 | |
| -1 | -376,388,233 |
Let's try dividing by 4:
376,388,233 ÷ 4 = 94,097,058.25
If the quotient is a whole number, then 4 and 94,097,058.25 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 | 376,388,233 | |
| -1 | 376,388,233 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 181 | 247 | 2,353 | 3,439 | 8,419 | 44,707 | 109,447 | 159,961 | 1,523,839 | 2,079,493 | 19,809,907 | 28,952,941 | 376,388,233 |
| -1 | -13 | -19 | -181 | -247 | -2,353 | -3,439 | -8,419 | -44,707 | -109,447 | -159,961 | -1,523,839 | -2,079,493 | -19,809,907 | -28,952,941 | -376,388,233 |
