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 130,323,037, 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 | 130,323,037 | |
| -1 | -130,323,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,323,037.
Example:
1 x 130,323,037 = 130,323,037
and
-1 x -130,323,037 = 130,323,037
Notice both answers equal 130,323,037
With that explanation out of the way, let's continue. Next, we take the number 130,323,037 and divide it by 2:
130,323,037 ÷ 2 = 65,161,518.5
If the quotient is a whole number, then 2 and 65,161,518.5 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 | 130,323,037 | |
| -1 | -130,323,037 |
Now, we try dividing 130,323,037 by 3:
130,323,037 ÷ 3 = 43,441,012.3333
If the quotient is a whole number, then 3 and 43,441,012.3333 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 | 130,323,037 | |
| -1 | -130,323,037 |
Let's try dividing by 4:
130,323,037 ÷ 4 = 32,580,759.25
If the quotient is a whole number, then 4 and 32,580,759.25 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 | 130,323,037 | |
| -1 | 130,323,037 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 23 | 221 | 299 | 391 | 5,083 | 25,639 | 333,307 | 435,863 | 589,697 | 5,666,219 | 7,666,061 | 10,024,849 | 130,323,037 |
| -1 | -13 | -17 | -23 | -221 | -299 | -391 | -5,083 | -25,639 | -333,307 | -435,863 | -589,697 | -5,666,219 | -7,666,061 | -10,024,849 | -130,323,037 |
