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 1,698,235, 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 | 1,698,235 | |
| -1 | -1,698,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,698,235.
Example:
1 x 1,698,235 = 1,698,235
and
-1 x -1,698,235 = 1,698,235
Notice both answers equal 1,698,235
With that explanation out of the way, let's continue. Next, we take the number 1,698,235 and divide it by 2:
1,698,235 ÷ 2 = 849,117.5
If the quotient is a whole number, then 2 and 849,117.5 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 | 1,698,235 | |
| -1 | -1,698,235 |
Now, we try dividing 1,698,235 by 3:
1,698,235 ÷ 3 = 566,078.3333
If the quotient is a whole number, then 3 and 566,078.3333 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 | 1,698,235 | |
| -1 | -1,698,235 |
Let's try dividing by 4:
1,698,235 ÷ 4 = 424,558.75
If the quotient is a whole number, then 4 and 424,558.75 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 | 1,698,235 | |
| -1 | 1,698,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 385 | 401 | 605 | 847 | 2,005 | 2,807 | 4,235 | 4,411 | 14,035 | 22,055 | 30,877 | 48,521 | 154,385 | 242,605 | 339,647 | 1,698,235 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -385 | -401 | -605 | -847 | -2,005 | -2,807 | -4,235 | -4,411 | -14,035 | -22,055 | -30,877 | -48,521 | -154,385 | -242,605 | -339,647 | -1,698,235 |
