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 3,645,719, 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 | 3,645,719 | |
| -1 | -3,645,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,645,719.
Example:
1 x 3,645,719 = 3,645,719
and
-1 x -3,645,719 = 3,645,719
Notice both answers equal 3,645,719
With that explanation out of the way, let's continue. Next, we take the number 3,645,719 and divide it by 2:
3,645,719 ÷ 2 = 1,822,859.5
If the quotient is a whole number, then 2 and 1,822,859.5 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 | 3,645,719 | |
| -1 | -3,645,719 |
Now, we try dividing 3,645,719 by 3:
3,645,719 ÷ 3 = 1,215,239.6667
If the quotient is a whole number, then 3 and 1,215,239.6667 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 | 3,645,719 | |
| -1 | -3,645,719 |
Let's try dividing by 4:
3,645,719 ÷ 4 = 911,429.75
If the quotient is a whole number, then 4 and 911,429.75 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 | 3,645,719 | |
| -1 | 3,645,719 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 419 | 791 | 1,243 | 2,933 | 4,609 | 8,701 | 32,263 | 47,347 | 331,429 | 520,817 | 3,645,719 |
| -1 | -7 | -11 | -77 | -113 | -419 | -791 | -1,243 | -2,933 | -4,609 | -8,701 | -32,263 | -47,347 | -331,429 | -520,817 | -3,645,719 |
