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 113,151,103, 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 | 113,151,103 | |
| -1 | -113,151,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,151,103.
Example:
1 x 113,151,103 = 113,151,103
and
-1 x -113,151,103 = 113,151,103
Notice both answers equal 113,151,103
With that explanation out of the way, let's continue. Next, we take the number 113,151,103 and divide it by 2:
113,151,103 ÷ 2 = 56,575,551.5
If the quotient is a whole number, then 2 and 56,575,551.5 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 | 113,151,103 | |
| -1 | -113,151,103 |
Now, we try dividing 113,151,103 by 3:
113,151,103 ÷ 3 = 37,717,034.3333
If the quotient is a whole number, then 3 and 37,717,034.3333 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 | 113,151,103 | |
| -1 | -113,151,103 |
Let's try dividing by 4:
113,151,103 ÷ 4 = 28,287,775.75
If the quotient is a whole number, then 4 and 28,287,775.75 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 | 113,151,103 | |
| -1 | 113,151,103 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 43 | 533 | 559 | 1,763 | 4,937 | 22,919 | 64,181 | 202,417 | 212,291 | 2,631,421 | 2,759,783 | 8,703,931 | 113,151,103 |
| -1 | -13 | -41 | -43 | -533 | -559 | -1,763 | -4,937 | -22,919 | -64,181 | -202,417 | -212,291 | -2,631,421 | -2,759,783 | -8,703,931 | -113,151,103 |
