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 3,166,219, 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 | 3,166,219 | |
| -1 | -3,166,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,166,219.
Example:
1 x 3,166,219 = 3,166,219
and
-1 x -3,166,219 = 3,166,219
Notice both answers equal 3,166,219
With that explanation out of the way, let's continue. Next, we take the number 3,166,219 and divide it by 2:
3,166,219 ÷ 2 = 1,583,109.5
If the quotient is a whole number, then 2 and 1,583,109.5 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 | 3,166,219 | |
| -1 | -3,166,219 |
Now, we try dividing 3,166,219 by 3:
3,166,219 ÷ 3 = 1,055,406.3333
If the quotient is a whole number, then 3 and 1,055,406.3333 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 | 3,166,219 | |
| -1 | -3,166,219 |
Let's try dividing by 4:
3,166,219 ÷ 4 = 791,554.75
If the quotient is a whole number, then 4 and 791,554.75 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 | 3,166,219 | |
| -1 | 3,166,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 67 | 157 | 301 | 469 | 1,099 | 2,881 | 6,751 | 10,519 | 20,167 | 47,257 | 73,633 | 452,317 | 3,166,219 |
| -1 | -7 | -43 | -67 | -157 | -301 | -469 | -1,099 | -2,881 | -6,751 | -10,519 | -20,167 | -47,257 | -73,633 | -452,317 | -3,166,219 |
