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 1,381,445, 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 | 1,381,445 | |
| -1 | -1,381,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,381,445.
Example:
1 x 1,381,445 = 1,381,445
and
-1 x -1,381,445 = 1,381,445
Notice both answers equal 1,381,445
With that explanation out of the way, let's continue. Next, we take the number 1,381,445 and divide it by 2:
1,381,445 ÷ 2 = 690,722.5
If the quotient is a whole number, then 2 and 690,722.5 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 | 1,381,445 | |
| -1 | -1,381,445 |
Now, we try dividing 1,381,445 by 3:
1,381,445 ÷ 3 = 460,481.6667
If the quotient is a whole number, then 3 and 460,481.6667 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 | 1,381,445 | |
| -1 | -1,381,445 |
Let's try dividing by 4:
1,381,445 ÷ 4 = 345,361.25
If the quotient is a whole number, then 4 and 345,361.25 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 | 1,381,445 | |
| -1 | 1,381,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 401 | 689 | 2,005 | 3,445 | 5,213 | 21,253 | 26,065 | 106,265 | 276,289 | 1,381,445 |
| -1 | -5 | -13 | -53 | -65 | -265 | -401 | -689 | -2,005 | -3,445 | -5,213 | -21,253 | -26,065 | -106,265 | -276,289 | -1,381,445 |
