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 1,349,803, 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 | 1,349,803 | |
| -1 | -1,349,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,349,803.
Example:
1 x 1,349,803 = 1,349,803
and
-1 x -1,349,803 = 1,349,803
Notice both answers equal 1,349,803
With that explanation out of the way, let's continue. Next, we take the number 1,349,803 and divide it by 2:
1,349,803 ÷ 2 = 674,901.5
If the quotient is a whole number, then 2 and 674,901.5 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 | 1,349,803 | |
| -1 | -1,349,803 |
Now, we try dividing 1,349,803 by 3:
1,349,803 ÷ 3 = 449,934.3333
If the quotient is a whole number, then 3 and 449,934.3333 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 | 1,349,803 | |
| -1 | -1,349,803 |
Let's try dividing by 4:
1,349,803 ÷ 4 = 337,450.75
If the quotient is a whole number, then 4 and 337,450.75 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 | 1,349,803 | |
| -1 | 1,349,803 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 163 | 169 | 637 | 1,141 | 1,183 | 2,119 | 7,987 | 8,281 | 14,833 | 27,547 | 103,831 | 192,829 | 1,349,803 |
| -1 | -7 | -13 | -49 | -91 | -163 | -169 | -637 | -1,141 | -1,183 | -2,119 | -7,987 | -8,281 | -14,833 | -27,547 | -103,831 | -192,829 | -1,349,803 |
