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 233,506,315, 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 | 233,506,315 | |
| -1 | -233,506,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,506,315.
Example:
1 x 233,506,315 = 233,506,315
and
-1 x -233,506,315 = 233,506,315
Notice both answers equal 233,506,315
With that explanation out of the way, let's continue. Next, we take the number 233,506,315 and divide it by 2:
233,506,315 ÷ 2 = 116,753,157.5
If the quotient is a whole number, then 2 and 116,753,157.5 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 | 233,506,315 | |
| -1 | -233,506,315 |
Now, we try dividing 233,506,315 by 3:
233,506,315 ÷ 3 = 77,835,438.3333
If the quotient is a whole number, then 3 and 77,835,438.3333 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 | 233,506,315 | |
| -1 | -233,506,315 |
Let's try dividing by 4:
233,506,315 ÷ 4 = 58,376,578.75
If the quotient is a whole number, then 4 and 58,376,578.75 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 | 233,506,315 | |
| -1 | 233,506,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 211 | 245 | 1,055 | 1,477 | 4,517 | 7,385 | 10,339 | 22,585 | 31,619 | 51,695 | 158,095 | 221,333 | 953,087 | 1,106,665 | 4,765,435 | 6,671,609 | 33,358,045 | 46,701,263 | 233,506,315 |
| -1 | -5 | -7 | -35 | -49 | -211 | -245 | -1,055 | -1,477 | -4,517 | -7,385 | -10,339 | -22,585 | -31,619 | -51,695 | -158,095 | -221,333 | -953,087 | -1,106,665 | -4,765,435 | -6,671,609 | -33,358,045 | -46,701,263 | -233,506,315 |
