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 130,213,433, 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 | 130,213,433 | |
| -1 | -130,213,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,213,433.
Example:
1 x 130,213,433 = 130,213,433
and
-1 x -130,213,433 = 130,213,433
Notice both answers equal 130,213,433
With that explanation out of the way, let's continue. Next, we take the number 130,213,433 and divide it by 2:
130,213,433 ÷ 2 = 65,106,716.5
If the quotient is a whole number, then 2 and 65,106,716.5 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 | 130,213,433 | |
| -1 | -130,213,433 |
Now, we try dividing 130,213,433 by 3:
130,213,433 ÷ 3 = 43,404,477.6667
If the quotient is a whole number, then 3 and 43,404,477.6667 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 | 130,213,433 | |
| -1 | -130,213,433 |
Let's try dividing by 4:
130,213,433 ÷ 4 = 32,553,358.25
If the quotient is a whole number, then 4 and 32,553,358.25 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 | 130,213,433 | |
| -1 | 130,213,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 193 | 281 | 343 | 1,351 | 1,967 | 2,401 | 9,457 | 13,769 | 54,233 | 66,199 | 96,383 | 379,631 | 463,393 | 674,681 | 2,657,417 | 18,601,919 | 130,213,433 |
| -1 | -7 | -49 | -193 | -281 | -343 | -1,351 | -1,967 | -2,401 | -9,457 | -13,769 | -54,233 | -66,199 | -96,383 | -379,631 | -463,393 | -674,681 | -2,657,417 | -18,601,919 | -130,213,433 |
