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 115,445,143, 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 | 115,445,143 | |
| -1 | -115,445,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,445,143.
Example:
1 x 115,445,143 = 115,445,143
and
-1 x -115,445,143 = 115,445,143
Notice both answers equal 115,445,143
With that explanation out of the way, let's continue. Next, we take the number 115,445,143 and divide it by 2:
115,445,143 ÷ 2 = 57,722,571.5
If the quotient is a whole number, then 2 and 57,722,571.5 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 | 115,445,143 | |
| -1 | -115,445,143 |
Now, we try dividing 115,445,143 by 3:
115,445,143 ÷ 3 = 38,481,714.3333
If the quotient is a whole number, then 3 and 38,481,714.3333 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 | 115,445,143 | |
| -1 | -115,445,143 |
Let's try dividing by 4:
115,445,143 ÷ 4 = 28,861,285.75
If the quotient is a whole number, then 4 and 28,861,285.75 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 | 115,445,143 | |
| -1 | 115,445,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 37 | 319 | 407 | 1,073 | 9,781 | 11,803 | 107,591 | 283,649 | 361,897 | 3,120,139 | 3,980,867 | 10,495,013 | 115,445,143 |
| -1 | -11 | -29 | -37 | -319 | -407 | -1,073 | -9,781 | -11,803 | -107,591 | -283,649 | -361,897 | -3,120,139 | -3,980,867 | -10,495,013 | -115,445,143 |
