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 3,019,159, 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 | 3,019,159 | |
| -1 | -3,019,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,019,159.
Example:
1 x 3,019,159 = 3,019,159
and
-1 x -3,019,159 = 3,019,159
Notice both answers equal 3,019,159
With that explanation out of the way, let's continue. Next, we take the number 3,019,159 and divide it by 2:
3,019,159 ÷ 2 = 1,509,579.5
If the quotient is a whole number, then 2 and 1,509,579.5 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 | 3,019,159 | |
| -1 | -3,019,159 |
Now, we try dividing 3,019,159 by 3:
3,019,159 ÷ 3 = 1,006,386.3333
If the quotient is a whole number, then 3 and 1,006,386.3333 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 | 3,019,159 | |
| -1 | -3,019,159 |
Let's try dividing by 4:
3,019,159 ÷ 4 = 754,789.75
If the quotient is a whole number, then 4 and 754,789.75 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 | 3,019,159 | |
| -1 | 3,019,159 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 43 | 143 | 473 | 491 | 559 | 5,401 | 6,149 | 6,383 | 21,113 | 70,213 | 232,243 | 274,469 | 3,019,159 |
| -1 | -11 | -13 | -43 | -143 | -473 | -491 | -559 | -5,401 | -6,149 | -6,383 | -21,113 | -70,213 | -232,243 | -274,469 | -3,019,159 |
