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 350,668,687, 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 | 350,668,687 | |
| -1 | -350,668,687 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,668,687.
Example:
1 x 350,668,687 = 350,668,687
and
-1 x -350,668,687 = 350,668,687
Notice both answers equal 350,668,687
With that explanation out of the way, let's continue. Next, we take the number 350,668,687 and divide it by 2:
350,668,687 ÷ 2 = 175,334,343.5
If the quotient is a whole number, then 2 and 175,334,343.5 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 | 350,668,687 | |
| -1 | -350,668,687 |
Now, we try dividing 350,668,687 by 3:
350,668,687 ÷ 3 = 116,889,562.3333
If the quotient is a whole number, then 3 and 116,889,562.3333 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 | 350,668,687 | |
| -1 | -350,668,687 |
Let's try dividing by 4:
350,668,687 ÷ 4 = 87,667,171.75
If the quotient is a whole number, then 4 and 87,667,171.75 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 | 350,668,687 | |
| -1 | 350,668,687 |
If you did it right, you will end up with this table:
| 1 | 61 | 67 | 239 | 359 | 4,087 | 14,579 | 16,013 | 21,899 | 24,053 | 85,801 | 976,793 | 1,467,233 | 5,233,861 | 5,748,667 | 350,668,687 |
| -1 | -61 | -67 | -239 | -359 | -4,087 | -14,579 | -16,013 | -21,899 | -24,053 | -85,801 | -976,793 | -1,467,233 | -5,233,861 | -5,748,667 | -350,668,687 |
