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 345,531,545, 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 | 345,531,545 | |
| -1 | -345,531,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,531,545.
Example:
1 x 345,531,545 = 345,531,545
and
-1 x -345,531,545 = 345,531,545
Notice both answers equal 345,531,545
With that explanation out of the way, let's continue. Next, we take the number 345,531,545 and divide it by 2:
345,531,545 ÷ 2 = 172,765,772.5
If the quotient is a whole number, then 2 and 172,765,772.5 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 | 345,531,545 | |
| -1 | -345,531,545 |
Now, we try dividing 345,531,545 by 3:
345,531,545 ÷ 3 = 115,177,181.6667
If the quotient is a whole number, then 3 and 115,177,181.6667 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 | 345,531,545 | |
| -1 | -345,531,545 |
Let's try dividing by 4:
345,531,545 ÷ 4 = 86,382,886.25
If the quotient is a whole number, then 4 and 86,382,886.25 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 | 345,531,545 | |
| -1 | 345,531,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 799 | 3,995 | 86,491 | 432,455 | 1,470,347 | 4,065,077 | 7,351,735 | 20,325,385 | 69,106,309 | 345,531,545 |
| -1 | -5 | -17 | -47 | -85 | -235 | -799 | -3,995 | -86,491 | -432,455 | -1,470,347 | -4,065,077 | -7,351,735 | -20,325,385 | -69,106,309 | -345,531,545 |
