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 345,425,509, 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 | 345,425,509 | |
| -1 | -345,425,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,425,509.
Example:
1 x 345,425,509 = 345,425,509
and
-1 x -345,425,509 = 345,425,509
Notice both answers equal 345,425,509
With that explanation out of the way, let's continue. Next, we take the number 345,425,509 and divide it by 2:
345,425,509 ÷ 2 = 172,712,754.5
If the quotient is a whole number, then 2 and 172,712,754.5 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 | 345,425,509 | |
| -1 | -345,425,509 |
Now, we try dividing 345,425,509 by 3:
345,425,509 ÷ 3 = 115,141,836.3333
If the quotient is a whole number, then 3 and 115,141,836.3333 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 | 345,425,509 | |
| -1 | -345,425,509 |
Let's try dividing by 4:
345,425,509 ÷ 4 = 86,356,377.25
If the quotient is a whole number, then 4 and 86,356,377.25 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 | 345,425,509 | |
| -1 | 345,425,509 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 709 | 3,407 | 7,799 | 9,217 | 37,477 | 44,291 | 101,387 | 487,201 | 2,415,563 | 26,571,193 | 31,402,319 | 345,425,509 |
| -1 | -11 | -13 | -143 | -709 | -3,407 | -7,799 | -9,217 | -37,477 | -44,291 | -101,387 | -487,201 | -2,415,563 | -26,571,193 | -31,402,319 | -345,425,509 |
