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 130,461,859, 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 | 130,461,859 | |
| -1 | -130,461,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,461,859.
Example:
1 x 130,461,859 = 130,461,859
and
-1 x -130,461,859 = 130,461,859
Notice both answers equal 130,461,859
With that explanation out of the way, let's continue. Next, we take the number 130,461,859 and divide it by 2:
130,461,859 ÷ 2 = 65,230,929.5
If the quotient is a whole number, then 2 and 65,230,929.5 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 | 130,461,859 | |
| -1 | -130,461,859 |
Now, we try dividing 130,461,859 by 3:
130,461,859 ÷ 3 = 43,487,286.3333
If the quotient is a whole number, then 3 and 43,487,286.3333 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 | 130,461,859 | |
| -1 | -130,461,859 |
Let's try dividing by 4:
130,461,859 ÷ 4 = 32,615,464.75
If the quotient is a whole number, then 4 and 32,615,464.75 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 | 130,461,859 | |
| -1 | 130,461,859 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 61 | 187 | 671 | 1,037 | 11,407 | 11,437 | 125,807 | 194,429 | 697,657 | 2,138,719 | 7,674,227 | 11,860,169 | 130,461,859 |
| -1 | -11 | -17 | -61 | -187 | -671 | -1,037 | -11,407 | -11,437 | -125,807 | -194,429 | -697,657 | -2,138,719 | -7,674,227 | -11,860,169 | -130,461,859 |
