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 130,034,345, 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 | 130,034,345 | |
| -1 | -130,034,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,034,345.
Example:
1 x 130,034,345 = 130,034,345
and
-1 x -130,034,345 = 130,034,345
Notice both answers equal 130,034,345
With that explanation out of the way, let's continue. Next, we take the number 130,034,345 and divide it by 2:
130,034,345 ÷ 2 = 65,017,172.5
If the quotient is a whole number, then 2 and 65,017,172.5 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 | 130,034,345 | |
| -1 | -130,034,345 |
Now, we try dividing 130,034,345 by 3:
130,034,345 ÷ 3 = 43,344,781.6667
If the quotient is a whole number, then 3 and 43,344,781.6667 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 | 130,034,345 | |
| -1 | -130,034,345 |
Let's try dividing by 4:
130,034,345 ÷ 4 = 32,508,586.25
If the quotient is a whole number, then 4 and 32,508,586.25 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 | 130,034,345 | |
| -1 | 130,034,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,229 | 3,023 | 6,145 | 8,603 | 15,115 | 21,161 | 43,015 | 105,805 | 3,715,267 | 18,576,335 | 26,006,869 | 130,034,345 |
| -1 | -5 | -7 | -35 | -1,229 | -3,023 | -6,145 | -8,603 | -15,115 | -21,161 | -43,015 | -105,805 | -3,715,267 | -18,576,335 | -26,006,869 | -130,034,345 |
