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 3,721,883, 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 | 3,721,883 | |
| -1 | -3,721,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,721,883.
Example:
1 x 3,721,883 = 3,721,883
and
-1 x -3,721,883 = 3,721,883
Notice both answers equal 3,721,883
With that explanation out of the way, let's continue. Next, we take the number 3,721,883 and divide it by 2:
3,721,883 ÷ 2 = 1,860,941.5
If the quotient is a whole number, then 2 and 1,860,941.5 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 | 3,721,883 | |
| -1 | -3,721,883 |
Now, we try dividing 3,721,883 by 3:
3,721,883 ÷ 3 = 1,240,627.6667
If the quotient is a whole number, then 3 and 1,240,627.6667 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 | 3,721,883 | |
| -1 | -3,721,883 |
Let's try dividing by 4:
3,721,883 ÷ 4 = 930,470.75
If the quotient is a whole number, then 4 and 930,470.75 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 | 3,721,883 | |
| -1 | 3,721,883 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 47 | 253 | 313 | 517 | 1,081 | 3,443 | 7,199 | 11,891 | 14,711 | 79,189 | 161,821 | 338,353 | 3,721,883 |
| -1 | -11 | -23 | -47 | -253 | -313 | -517 | -1,081 | -3,443 | -7,199 | -11,891 | -14,711 | -79,189 | -161,821 | -338,353 | -3,721,883 |
