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 3,893,527, 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 | 3,893,527 | |
| -1 | -3,893,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,893,527.
Example:
1 x 3,893,527 = 3,893,527
and
-1 x -3,893,527 = 3,893,527
Notice both answers equal 3,893,527
With that explanation out of the way, let's continue. Next, we take the number 3,893,527 and divide it by 2:
3,893,527 ÷ 2 = 1,946,763.5
If the quotient is a whole number, then 2 and 1,946,763.5 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 | 3,893,527 | |
| -1 | -3,893,527 |
Now, we try dividing 3,893,527 by 3:
3,893,527 ÷ 3 = 1,297,842.3333
If the quotient is a whole number, then 3 and 1,297,842.3333 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 | 3,893,527 | |
| -1 | -3,893,527 |
Let's try dividing by 4:
3,893,527 ÷ 4 = 973,381.75
If the quotient is a whole number, then 4 and 973,381.75 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 | 3,893,527 | |
| -1 | 3,893,527 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 47 | 187 | 443 | 517 | 799 | 4,873 | 7,531 | 8,789 | 20,821 | 82,841 | 229,031 | 353,957 | 3,893,527 |
| -1 | -11 | -17 | -47 | -187 | -443 | -517 | -799 | -4,873 | -7,531 | -8,789 | -20,821 | -82,841 | -229,031 | -353,957 | -3,893,527 |
