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 1,112,945, 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 | 1,112,945 | |
| -1 | -1,112,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,112,945.
Example:
1 x 1,112,945 = 1,112,945
and
-1 x -1,112,945 = 1,112,945
Notice both answers equal 1,112,945
With that explanation out of the way, let's continue. Next, we take the number 1,112,945 and divide it by 2:
1,112,945 ÷ 2 = 556,472.5
If the quotient is a whole number, then 2 and 556,472.5 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 | 1,112,945 | |
| -1 | -1,112,945 |
Now, we try dividing 1,112,945 by 3:
1,112,945 ÷ 3 = 370,981.6667
If the quotient is a whole number, then 3 and 370,981.6667 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 | 1,112,945 | |
| -1 | -1,112,945 |
Let's try dividing by 4:
1,112,945 ÷ 4 = 278,236.25
If the quotient is a whole number, then 4 and 278,236.25 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 | 1,112,945 | |
| -1 | 1,112,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 61 | 89 | 205 | 305 | 445 | 2,501 | 3,649 | 5,429 | 12,505 | 18,245 | 27,145 | 222,589 | 1,112,945 |
| -1 | -5 | -41 | -61 | -89 | -205 | -305 | -445 | -2,501 | -3,649 | -5,429 | -12,505 | -18,245 | -27,145 | -222,589 | -1,112,945 |
