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 3,378,739, 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 | 3,378,739 | |
| -1 | -3,378,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,378,739.
Example:
1 x 3,378,739 = 3,378,739
and
-1 x -3,378,739 = 3,378,739
Notice both answers equal 3,378,739
With that explanation out of the way, let's continue. Next, we take the number 3,378,739 and divide it by 2:
3,378,739 ÷ 2 = 1,689,369.5
If the quotient is a whole number, then 2 and 1,689,369.5 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 | 3,378,739 | |
| -1 | -3,378,739 |
Now, we try dividing 3,378,739 by 3:
3,378,739 ÷ 3 = 1,126,246.3333
If the quotient is a whole number, then 3 and 1,126,246.3333 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 | 3,378,739 | |
| -1 | -3,378,739 |
Let's try dividing by 4:
3,378,739 ÷ 4 = 844,684.75
If the quotient is a whole number, then 4 and 844,684.75 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 | 3,378,739 | |
| -1 | 3,378,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 107 | 347 | 749 | 1,391 | 2,429 | 4,511 | 9,737 | 31,577 | 37,129 | 259,903 | 482,677 | 3,378,739 |
| -1 | -7 | -13 | -91 | -107 | -347 | -749 | -1,391 | -2,429 | -4,511 | -9,737 | -31,577 | -37,129 | -259,903 | -482,677 | -3,378,739 |
