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 113,341,151, 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 | 113,341,151 | |
| -1 | -113,341,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,341,151.
Example:
1 x 113,341,151 = 113,341,151
and
-1 x -113,341,151 = 113,341,151
Notice both answers equal 113,341,151
With that explanation out of the way, let's continue. Next, we take the number 113,341,151 and divide it by 2:
113,341,151 ÷ 2 = 56,670,575.5
If the quotient is a whole number, then 2 and 56,670,575.5 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 | 113,341,151 | |
| -1 | -113,341,151 |
Now, we try dividing 113,341,151 by 3:
113,341,151 ÷ 3 = 37,780,383.6667
If the quotient is a whole number, then 3 and 37,780,383.6667 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 | 113,341,151 | |
| -1 | -113,341,151 |
Let's try dividing by 4:
113,341,151 ÷ 4 = 28,335,287.75
If the quotient is a whole number, then 4 and 28,335,287.75 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 | 113,341,151 | |
| -1 | 113,341,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 311 | 2,177 | 3,421 | 4,733 | 23,947 | 33,131 | 52,063 | 364,441 | 1,471,963 | 10,303,741 | 16,191,593 | 113,341,151 |
| -1 | -7 | -11 | -77 | -311 | -2,177 | -3,421 | -4,733 | -23,947 | -33,131 | -52,063 | -364,441 | -1,471,963 | -10,303,741 | -16,191,593 | -113,341,151 |
