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 1,120,175, 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 | 1,120,175 | |
| -1 | -1,120,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,120,175.
Example:
1 x 1,120,175 = 1,120,175
and
-1 x -1,120,175 = 1,120,175
Notice both answers equal 1,120,175
With that explanation out of the way, let's continue. Next, we take the number 1,120,175 and divide it by 2:
1,120,175 ÷ 2 = 560,087.5
If the quotient is a whole number, then 2 and 560,087.5 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 | 1,120,175 | |
| -1 | -1,120,175 |
Now, we try dividing 1,120,175 by 3:
1,120,175 ÷ 3 = 373,391.6667
If the quotient is a whole number, then 3 and 373,391.6667 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 | 1,120,175 | |
| -1 | -1,120,175 |
Let's try dividing by 4:
1,120,175 ÷ 4 = 280,043.75
If the quotient is a whole number, then 4 and 280,043.75 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 | 1,120,175 | |
| -1 | 1,120,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 37 | 173 | 175 | 185 | 259 | 865 | 925 | 1,211 | 1,295 | 4,325 | 6,055 | 6,401 | 6,475 | 30,275 | 32,005 | 44,807 | 160,025 | 224,035 | 1,120,175 |
| -1 | -5 | -7 | -25 | -35 | -37 | -173 | -175 | -185 | -259 | -865 | -925 | -1,211 | -1,295 | -4,325 | -6,055 | -6,401 | -6,475 | -30,275 | -32,005 | -44,807 | -160,025 | -224,035 | -1,120,175 |
