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 1,364,155, 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 | 1,364,155 | |
| -1 | -1,364,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,364,155.
Example:
1 x 1,364,155 = 1,364,155
and
-1 x -1,364,155 = 1,364,155
Notice both answers equal 1,364,155
With that explanation out of the way, let's continue. Next, we take the number 1,364,155 and divide it by 2:
1,364,155 ÷ 2 = 682,077.5
If the quotient is a whole number, then 2 and 682,077.5 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 | 1,364,155 | |
| -1 | -1,364,155 |
Now, we try dividing 1,364,155 by 3:
1,364,155 ÷ 3 = 454,718.3333
If the quotient is a whole number, then 3 and 454,718.3333 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 | 1,364,155 | |
| -1 | -1,364,155 |
Let's try dividing by 4:
1,364,155 ÷ 4 = 341,038.75
If the quotient is a whole number, then 4 and 341,038.75 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 | 1,364,155 | |
| -1 | 1,364,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 677 | 2,015 | 3,385 | 8,801 | 20,987 | 44,005 | 104,935 | 272,831 | 1,364,155 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -677 | -2,015 | -3,385 | -8,801 | -20,987 | -44,005 | -104,935 | -272,831 | -1,364,155 |
