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 130,014,325, 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 | 130,014,325 | |
| -1 | -130,014,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,014,325.
Example:
1 x 130,014,325 = 130,014,325
and
-1 x -130,014,325 = 130,014,325
Notice both answers equal 130,014,325
With that explanation out of the way, let's continue. Next, we take the number 130,014,325 and divide it by 2:
130,014,325 ÷ 2 = 65,007,162.5
If the quotient is a whole number, then 2 and 65,007,162.5 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 | 130,014,325 | |
| -1 | -130,014,325 |
Now, we try dividing 130,014,325 by 3:
130,014,325 ÷ 3 = 43,338,108.3333
If the quotient is a whole number, then 3 and 43,338,108.3333 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 | 130,014,325 | |
| -1 | -130,014,325 |
Let's try dividing by 4:
130,014,325 ÷ 4 = 32,503,581.25
If the quotient is a whole number, then 4 and 32,503,581.25 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 | 130,014,325 | |
| -1 | 130,014,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 103 | 175 | 515 | 721 | 2,575 | 3,605 | 7,213 | 18,025 | 36,065 | 50,491 | 180,325 | 252,455 | 742,939 | 1,262,275 | 3,714,695 | 5,200,573 | 18,573,475 | 26,002,865 | 130,014,325 |
| -1 | -5 | -7 | -25 | -35 | -103 | -175 | -515 | -721 | -2,575 | -3,605 | -7,213 | -18,025 | -36,065 | -50,491 | -180,325 | -252,455 | -742,939 | -1,262,275 | -3,714,695 | -5,200,573 | -18,573,475 | -26,002,865 | -130,014,325 |
