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 130,121,341, 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 | 130,121,341 | |
| -1 | -130,121,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,121,341.
Example:
1 x 130,121,341 = 130,121,341
and
-1 x -130,121,341 = 130,121,341
Notice both answers equal 130,121,341
With that explanation out of the way, let's continue. Next, we take the number 130,121,341 and divide it by 2:
130,121,341 ÷ 2 = 65,060,670.5
If the quotient is a whole number, then 2 and 65,060,670.5 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 | 130,121,341 | |
| -1 | -130,121,341 |
Now, we try dividing 130,121,341 by 3:
130,121,341 ÷ 3 = 43,373,780.3333
If the quotient is a whole number, then 3 and 43,373,780.3333 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 | 130,121,341 | |
| -1 | -130,121,341 |
Let's try dividing by 4:
130,121,341 ÷ 4 = 32,530,335.25
If the quotient is a whole number, then 4 and 32,530,335.25 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 | 130,121,341 | |
| -1 | 130,121,341 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 83 | 259 | 581 | 3,071 | 6,053 | 21,497 | 42,371 | 223,961 | 502,399 | 1,567,727 | 3,516,793 | 18,588,763 | 130,121,341 |
| -1 | -7 | -37 | -83 | -259 | -581 | -3,071 | -6,053 | -21,497 | -42,371 | -223,961 | -502,399 | -1,567,727 | -3,516,793 | -18,588,763 | -130,121,341 |
