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 351,435,139, 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 | 351,435,139 | |
| -1 | -351,435,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,435,139.
Example:
1 x 351,435,139 = 351,435,139
and
-1 x -351,435,139 = 351,435,139
Notice both answers equal 351,435,139
With that explanation out of the way, let's continue. Next, we take the number 351,435,139 and divide it by 2:
351,435,139 ÷ 2 = 175,717,569.5
If the quotient is a whole number, then 2 and 175,717,569.5 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 | 351,435,139 | |
| -1 | -351,435,139 |
Now, we try dividing 351,435,139 by 3:
351,435,139 ÷ 3 = 117,145,046.3333
If the quotient is a whole number, then 3 and 117,145,046.3333 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 | 351,435,139 | |
| -1 | -351,435,139 |
Let's try dividing by 4:
351,435,139 ÷ 4 = 87,858,784.75
If the quotient is a whole number, then 4 and 87,858,784.75 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 | 351,435,139 | |
| -1 | 351,435,139 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 407 | 587 | 1,471 | 6,457 | 16,181 | 21,719 | 54,427 | 238,909 | 598,697 | 863,477 | 9,498,247 | 31,948,649 | 351,435,139 |
| -1 | -11 | -37 | -407 | -587 | -1,471 | -6,457 | -16,181 | -21,719 | -54,427 | -238,909 | -598,697 | -863,477 | -9,498,247 | -31,948,649 | -351,435,139 |
