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 233,112,451, 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 | 233,112,451 | |
| -1 | -233,112,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,112,451.
Example:
1 x 233,112,451 = 233,112,451
and
-1 x -233,112,451 = 233,112,451
Notice both answers equal 233,112,451
With that explanation out of the way, let's continue. Next, we take the number 233,112,451 and divide it by 2:
233,112,451 ÷ 2 = 116,556,225.5
If the quotient is a whole number, then 2 and 116,556,225.5 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 | 233,112,451 | |
| -1 | -233,112,451 |
Now, we try dividing 233,112,451 by 3:
233,112,451 ÷ 3 = 77,704,150.3333
If the quotient is a whole number, then 3 and 77,704,150.3333 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 | 233,112,451 | |
| -1 | -233,112,451 |
Let's try dividing by 4:
233,112,451 ÷ 4 = 58,278,112.75
If the quotient is a whole number, then 4 and 58,278,112.75 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 | 233,112,451 | |
| -1 | 233,112,451 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 593 | 2,749 | 6,523 | 7,709 | 30,239 | 35,737 | 84,799 | 393,107 | 1,630,157 | 17,931,727 | 21,192,041 | 233,112,451 |
| -1 | -11 | -13 | -143 | -593 | -2,749 | -6,523 | -7,709 | -30,239 | -35,737 | -84,799 | -393,107 | -1,630,157 | -17,931,727 | -21,192,041 | -233,112,451 |
