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 130,567,115, 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 | 130,567,115 | |
| -1 | -130,567,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,567,115.
Example:
1 x 130,567,115 = 130,567,115
and
-1 x -130,567,115 = 130,567,115
Notice both answers equal 130,567,115
With that explanation out of the way, let's continue. Next, we take the number 130,567,115 and divide it by 2:
130,567,115 ÷ 2 = 65,283,557.5
If the quotient is a whole number, then 2 and 65,283,557.5 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 | 130,567,115 | |
| -1 | -130,567,115 |
Now, we try dividing 130,567,115 by 3:
130,567,115 ÷ 3 = 43,522,371.6667
If the quotient is a whole number, then 3 and 43,522,371.6667 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 | 130,567,115 | |
| -1 | -130,567,115 |
Let's try dividing by 4:
130,567,115 ÷ 4 = 32,641,778.75
If the quotient is a whole number, then 4 and 32,641,778.75 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 | 130,567,115 | |
| -1 | 130,567,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 409 | 1,303 | 2,045 | 2,863 | 6,515 | 9,121 | 14,315 | 20,041 | 45,605 | 63,847 | 100,205 | 319,235 | 532,927 | 2,664,635 | 3,730,489 | 18,652,445 | 26,113,423 | 130,567,115 |
| -1 | -5 | -7 | -35 | -49 | -245 | -409 | -1,303 | -2,045 | -2,863 | -6,515 | -9,121 | -14,315 | -20,041 | -45,605 | -63,847 | -100,205 | -319,235 | -532,927 | -2,664,635 | -3,730,489 | -18,652,445 | -26,113,423 | -130,567,115 |
