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 1,546,415, 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 | 1,546,415 | |
| -1 | -1,546,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,546,415.
Example:
1 x 1,546,415 = 1,546,415
and
-1 x -1,546,415 = 1,546,415
Notice both answers equal 1,546,415
With that explanation out of the way, let's continue. Next, we take the number 1,546,415 and divide it by 2:
1,546,415 ÷ 2 = 773,207.5
If the quotient is a whole number, then 2 and 773,207.5 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 | 1,546,415 | |
| -1 | -1,546,415 |
Now, we try dividing 1,546,415 by 3:
1,546,415 ÷ 3 = 515,471.6667
If the quotient is a whole number, then 3 and 515,471.6667 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 | 1,546,415 | |
| -1 | -1,546,415 |
Let's try dividing by 4:
1,546,415 ÷ 4 = 386,603.75
If the quotient is a whole number, then 4 and 386,603.75 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 | 1,546,415 | |
| -1 | 1,546,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 643 | 2,405 | 3,215 | 8,359 | 23,791 | 41,795 | 118,955 | 309,283 | 1,546,415 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -643 | -2,405 | -3,215 | -8,359 | -23,791 | -41,795 | -118,955 | -309,283 | -1,546,415 |
