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 1,448,161, 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 | 1,448,161 | |
| -1 | -1,448,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,448,161.
Example:
1 x 1,448,161 = 1,448,161
and
-1 x -1,448,161 = 1,448,161
Notice both answers equal 1,448,161
With that explanation out of the way, let's continue. Next, we take the number 1,448,161 and divide it by 2:
1,448,161 ÷ 2 = 724,080.5
If the quotient is a whole number, then 2 and 724,080.5 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 | 1,448,161 | |
| -1 | -1,448,161 |
Now, we try dividing 1,448,161 by 3:
1,448,161 ÷ 3 = 482,720.3333
If the quotient is a whole number, then 3 and 482,720.3333 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 | 1,448,161 | |
| -1 | -1,448,161 |
Let's try dividing by 4:
1,448,161 ÷ 4 = 362,040.25
If the quotient is a whole number, then 4 and 362,040.25 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 | 1,448,161 | |
| -1 | 1,448,161 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 41 | 143 | 169 | 209 | 247 | 451 | 533 | 779 | 1,859 | 2,717 | 3,211 | 5,863 | 6,929 | 8,569 | 10,127 | 35,321 | 76,219 | 111,397 | 131,651 | 1,448,161 |
| -1 | -11 | -13 | -19 | -41 | -143 | -169 | -209 | -247 | -451 | -533 | -779 | -1,859 | -2,717 | -3,211 | -5,863 | -6,929 | -8,569 | -10,127 | -35,321 | -76,219 | -111,397 | -131,651 | -1,448,161 |
