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 113,151,415, 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 | 113,151,415 | |
| -1 | -113,151,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,151,415.
Example:
1 x 113,151,415 = 113,151,415
and
-1 x -113,151,415 = 113,151,415
Notice both answers equal 113,151,415
With that explanation out of the way, let's continue. Next, we take the number 113,151,415 and divide it by 2:
113,151,415 ÷ 2 = 56,575,707.5
If the quotient is a whole number, then 2 and 56,575,707.5 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 | 113,151,415 | |
| -1 | -113,151,415 |
Now, we try dividing 113,151,415 by 3:
113,151,415 ÷ 3 = 37,717,138.3333
If the quotient is a whole number, then 3 and 37,717,138.3333 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 | 113,151,415 | |
| -1 | -113,151,415 |
Let's try dividing by 4:
113,151,415 ÷ 4 = 28,287,853.75
If the quotient is a whole number, then 4 and 28,287,853.75 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 | 113,151,415 | |
| -1 | 113,151,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 169 | 359 | 373 | 845 | 1,795 | 1,865 | 4,667 | 4,849 | 23,335 | 24,245 | 60,671 | 63,037 | 133,907 | 303,355 | 315,185 | 669,535 | 1,740,791 | 8,703,955 | 22,630,283 | 113,151,415 |
| -1 | -5 | -13 | -65 | -169 | -359 | -373 | -845 | -1,795 | -1,865 | -4,667 | -4,849 | -23,335 | -24,245 | -60,671 | -63,037 | -133,907 | -303,355 | -315,185 | -669,535 | -1,740,791 | -8,703,955 | -22,630,283 | -113,151,415 |
