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 130,462,145, 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 | 130,462,145 | |
| -1 | -130,462,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,462,145.
Example:
1 x 130,462,145 = 130,462,145
and
-1 x -130,462,145 = 130,462,145
Notice both answers equal 130,462,145
With that explanation out of the way, let's continue. Next, we take the number 130,462,145 and divide it by 2:
130,462,145 ÷ 2 = 65,231,072.5
If the quotient is a whole number, then 2 and 65,231,072.5 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 | 130,462,145 | |
| -1 | -130,462,145 |
Now, we try dividing 130,462,145 by 3:
130,462,145 ÷ 3 = 43,487,381.6667
If the quotient is a whole number, then 3 and 43,487,381.6667 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 | 130,462,145 | |
| -1 | -130,462,145 |
Let's try dividing by 4:
130,462,145 ÷ 4 = 32,615,536.25
If the quotient is a whole number, then 4 and 32,615,536.25 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 | 130,462,145 | |
| -1 | 130,462,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 71 | 355 | 781 | 3,905 | 33,409 | 167,045 | 367,499 | 1,837,495 | 2,372,039 | 11,860,195 | 26,092,429 | 130,462,145 |
| -1 | -5 | -11 | -55 | -71 | -355 | -781 | -3,905 | -33,409 | -167,045 | -367,499 | -1,837,495 | -2,372,039 | -11,860,195 | -26,092,429 | -130,462,145 |
