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 3,180,463, 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 | 3,180,463 | |
| -1 | -3,180,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,180,463.
Example:
1 x 3,180,463 = 3,180,463
and
-1 x -3,180,463 = 3,180,463
Notice both answers equal 3,180,463
With that explanation out of the way, let's continue. Next, we take the number 3,180,463 and divide it by 2:
3,180,463 ÷ 2 = 1,590,231.5
If the quotient is a whole number, then 2 and 1,590,231.5 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 | 3,180,463 | |
| -1 | -3,180,463 |
Now, we try dividing 3,180,463 by 3:
3,180,463 ÷ 3 = 1,060,154.3333
If the quotient is a whole number, then 3 and 1,060,154.3333 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 | 3,180,463 | |
| -1 | -3,180,463 |
Let's try dividing by 4:
3,180,463 ÷ 4 = 795,115.75
If the quotient is a whole number, then 4 and 795,115.75 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 | 3,180,463 | |
| -1 | 3,180,463 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 967 | 3,289 | 10,637 | 12,571 | 22,241 | 138,281 | 244,651 | 289,133 | 3,180,463 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -967 | -3,289 | -10,637 | -12,571 | -22,241 | -138,281 | -244,651 | -289,133 | -3,180,463 |
