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 3,967,477, 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 | 3,967,477 | |
| -1 | -3,967,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,967,477.
Example:
1 x 3,967,477 = 3,967,477
and
-1 x -3,967,477 = 3,967,477
Notice both answers equal 3,967,477
With that explanation out of the way, let's continue. Next, we take the number 3,967,477 and divide it by 2:
3,967,477 ÷ 2 = 1,983,738.5
If the quotient is a whole number, then 2 and 1,983,738.5 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 | 3,967,477 | |
| -1 | -3,967,477 |
Now, we try dividing 3,967,477 by 3:
3,967,477 ÷ 3 = 1,322,492.3333
If the quotient is a whole number, then 3 and 1,322,492.3333 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 | 3,967,477 | |
| -1 | -3,967,477 |
Let's try dividing by 4:
3,967,477 ÷ 4 = 991,869.25
If the quotient is a whole number, then 4 and 991,869.25 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 | 3,967,477 | |
| -1 | 3,967,477 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 73 | 139 | 391 | 1,241 | 1,679 | 2,363 | 3,197 | 10,147 | 28,543 | 54,349 | 172,499 | 233,381 | 3,967,477 |
| -1 | -17 | -23 | -73 | -139 | -391 | -1,241 | -1,679 | -2,363 | -3,197 | -10,147 | -28,543 | -54,349 | -172,499 | -233,381 | -3,967,477 |
