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 3,490,565, 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 | 3,490,565 | |
| -1 | -3,490,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,490,565.
Example:
1 x 3,490,565 = 3,490,565
and
-1 x -3,490,565 = 3,490,565
Notice both answers equal 3,490,565
With that explanation out of the way, let's continue. Next, we take the number 3,490,565 and divide it by 2:
3,490,565 ÷ 2 = 1,745,282.5
If the quotient is a whole number, then 2 and 1,745,282.5 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 | 3,490,565 | |
| -1 | -3,490,565 |
Now, we try dividing 3,490,565 by 3:
3,490,565 ÷ 3 = 1,163,521.6667
If the quotient is a whole number, then 3 and 1,163,521.6667 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 | 3,490,565 | |
| -1 | -3,490,565 |
Let's try dividing by 4:
3,490,565 ÷ 4 = 872,641.25
If the quotient is a whole number, then 4 and 872,641.25 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 | 3,490,565 | |
| -1 | 3,490,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 415 | 647 | 1,079 | 3,235 | 5,395 | 8,411 | 42,055 | 53,701 | 268,505 | 698,113 | 3,490,565 |
| -1 | -5 | -13 | -65 | -83 | -415 | -647 | -1,079 | -3,235 | -5,395 | -8,411 | -42,055 | -53,701 | -268,505 | -698,113 | -3,490,565 |
