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 130,046,305, 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 | 130,046,305 | |
| -1 | -130,046,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,046,305.
Example:
1 x 130,046,305 = 130,046,305
and
-1 x -130,046,305 = 130,046,305
Notice both answers equal 130,046,305
With that explanation out of the way, let's continue. Next, we take the number 130,046,305 and divide it by 2:
130,046,305 ÷ 2 = 65,023,152.5
If the quotient is a whole number, then 2 and 65,023,152.5 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 | 130,046,305 | |
| -1 | -130,046,305 |
Now, we try dividing 130,046,305 by 3:
130,046,305 ÷ 3 = 43,348,768.3333
If the quotient is a whole number, then 3 and 43,348,768.3333 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 | 130,046,305 | |
| -1 | -130,046,305 |
Let's try dividing by 4:
130,046,305 ÷ 4 = 32,511,576.25
If the quotient is a whole number, then 4 and 32,511,576.25 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 | 130,046,305 | |
| -1 | 130,046,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 401 | 1,753 | 2,005 | 8,765 | 14,837 | 64,861 | 74,185 | 324,305 | 702,953 | 3,514,765 | 26,009,261 | 130,046,305 |
| -1 | -5 | -37 | -185 | -401 | -1,753 | -2,005 | -8,765 | -14,837 | -64,861 | -74,185 | -324,305 | -702,953 | -3,514,765 | -26,009,261 | -130,046,305 |
