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 130,230,035, 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 | 130,230,035 | |
| -1 | -130,230,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,230,035.
Example:
1 x 130,230,035 = 130,230,035
and
-1 x -130,230,035 = 130,230,035
Notice both answers equal 130,230,035
With that explanation out of the way, let's continue. Next, we take the number 130,230,035 and divide it by 2:
130,230,035 ÷ 2 = 65,115,017.5
If the quotient is a whole number, then 2 and 65,115,017.5 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 | 130,230,035 | |
| -1 | -130,230,035 |
Now, we try dividing 130,230,035 by 3:
130,230,035 ÷ 3 = 43,410,011.6667
If the quotient is a whole number, then 3 and 43,410,011.6667 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 | 130,230,035 | |
| -1 | -130,230,035 |
Let's try dividing by 4:
130,230,035 ÷ 4 = 32,557,508.75
If the quotient is a whole number, then 4 and 32,557,508.75 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 | 130,230,035 | |
| -1 | 130,230,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 421 | 2,105 | 4,759 | 5,473 | 23,795 | 27,365 | 61,867 | 309,335 | 2,003,539 | 10,017,695 | 26,046,007 | 130,230,035 |
| -1 | -5 | -13 | -65 | -421 | -2,105 | -4,759 | -5,473 | -23,795 | -27,365 | -61,867 | -309,335 | -2,003,539 | -10,017,695 | -26,046,007 | -130,230,035 |
