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 112,280,315, 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 | 112,280,315 | |
| -1 | -112,280,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,280,315.
Example:
1 x 112,280,315 = 112,280,315
and
-1 x -112,280,315 = 112,280,315
Notice both answers equal 112,280,315
With that explanation out of the way, let's continue. Next, we take the number 112,280,315 and divide it by 2:
112,280,315 ÷ 2 = 56,140,157.5
If the quotient is a whole number, then 2 and 56,140,157.5 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 | 112,280,315 | |
| -1 | -112,280,315 |
Now, we try dividing 112,280,315 by 3:
112,280,315 ÷ 3 = 37,426,771.6667
If the quotient is a whole number, then 3 and 37,426,771.6667 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 | 112,280,315 | |
| -1 | -112,280,315 |
Let's try dividing by 4:
112,280,315 ÷ 4 = 28,070,078.75
If the quotient is a whole number, then 4 and 28,070,078.75 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 | 112,280,315 | |
| -1 | 112,280,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 49 | 145 | 203 | 245 | 1,015 | 1,421 | 7,105 | 15,803 | 79,015 | 110,621 | 458,287 | 553,105 | 774,347 | 2,291,435 | 3,208,009 | 3,871,735 | 16,040,045 | 22,456,063 | 112,280,315 |
| -1 | -5 | -7 | -29 | -35 | -49 | -145 | -203 | -245 | -1,015 | -1,421 | -7,105 | -15,803 | -79,015 | -110,621 | -458,287 | -553,105 | -774,347 | -2,291,435 | -3,208,009 | -3,871,735 | -16,040,045 | -22,456,063 | -112,280,315 |
