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 448,105, 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 | 448,105 | |
| -1 | -448,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 448,105.
Example:
1 x 448,105 = 448,105
and
-1 x -448,105 = 448,105
Notice both answers equal 448,105
With that explanation out of the way, let's continue. Next, we take the number 448,105 and divide it by 2:
448,105 ÷ 2 = 224,052.5
If the quotient is a whole number, then 2 and 224,052.5 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 | 448,105 | |
| -1 | -448,105 |
Now, we try dividing 448,105 by 3:
448,105 ÷ 3 = 149,368.3333
If the quotient is a whole number, then 3 and 149,368.3333 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 | 448,105 | |
| -1 | -448,105 |
Let's try dividing by 4:
448,105 ÷ 4 = 112,026.25
If the quotient is a whole number, then 4 and 112,026.25 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 | 448,105 | |
| -1 | 448,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 59 | 155 | 217 | 245 | 295 | 413 | 1,085 | 1,519 | 1,829 | 2,065 | 2,891 | 7,595 | 9,145 | 12,803 | 14,455 | 64,015 | 89,621 | 448,105 |
| -1 | -5 | -7 | -31 | -35 | -49 | -59 | -155 | -217 | -245 | -295 | -413 | -1,085 | -1,519 | -1,829 | -2,065 | -2,891 | -7,595 | -9,145 | -12,803 | -14,455 | -64,015 | -89,621 | -448,105 |
