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 345,865,685, 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 | 345,865,685 | |
| -1 | -345,865,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,865,685.
Example:
1 x 345,865,685 = 345,865,685
and
-1 x -345,865,685 = 345,865,685
Notice both answers equal 345,865,685
With that explanation out of the way, let's continue. Next, we take the number 345,865,685 and divide it by 2:
345,865,685 ÷ 2 = 172,932,842.5
If the quotient is a whole number, then 2 and 172,932,842.5 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 | 345,865,685 | |
| -1 | -345,865,685 |
Now, we try dividing 345,865,685 by 3:
345,865,685 ÷ 3 = 115,288,561.6667
If the quotient is a whole number, then 3 and 115,288,561.6667 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 | 345,865,685 | |
| -1 | -345,865,685 |
Let's try dividing by 4:
345,865,685 ÷ 4 = 86,466,421.25
If the quotient is a whole number, then 4 and 86,466,421.25 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 | 345,865,685 | |
| -1 | 345,865,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,523 | 4,129 | 7,615 | 16,753 | 20,645 | 45,419 | 83,765 | 227,095 | 6,288,467 | 31,442,335 | 69,173,137 | 345,865,685 |
| -1 | -5 | -11 | -55 | -1,523 | -4,129 | -7,615 | -16,753 | -20,645 | -45,419 | -83,765 | -227,095 | -6,288,467 | -31,442,335 | -69,173,137 | -345,865,685 |
