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 3,421,733, 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 | 3,421,733 | |
| -1 | -3,421,733 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,421,733.
Example:
1 x 3,421,733 = 3,421,733
and
-1 x -3,421,733 = 3,421,733
Notice both answers equal 3,421,733
With that explanation out of the way, let's continue. Next, we take the number 3,421,733 and divide it by 2:
3,421,733 ÷ 2 = 1,710,866.5
If the quotient is a whole number, then 2 and 1,710,866.5 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 | 3,421,733 | |
| -1 | -3,421,733 |
Now, we try dividing 3,421,733 by 3:
3,421,733 ÷ 3 = 1,140,577.6667
If the quotient is a whole number, then 3 and 1,140,577.6667 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 | 3,421,733 | |
| -1 | -3,421,733 |
Let's try dividing by 4:
3,421,733 ÷ 4 = 855,433.25
If the quotient is a whole number, then 4 and 855,433.25 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 | 3,421,733 | |
| -1 | 3,421,733 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 53 | 161 | 371 | 401 | 1,219 | 2,807 | 8,533 | 9,223 | 21,253 | 64,561 | 148,771 | 488,819 | 3,421,733 |
| -1 | -7 | -23 | -53 | -161 | -371 | -401 | -1,219 | -2,807 | -8,533 | -9,223 | -21,253 | -64,561 | -148,771 | -488,819 | -3,421,733 |
