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 10,477,397, 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 | 10,477,397 | |
| -1 | -10,477,397 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,477,397.
Example:
1 x 10,477,397 = 10,477,397
and
-1 x -10,477,397 = 10,477,397
Notice both answers equal 10,477,397
With that explanation out of the way, let's continue. Next, we take the number 10,477,397 and divide it by 2:
10,477,397 ÷ 2 = 5,238,698.5
If the quotient is a whole number, then 2 and 5,238,698.5 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 | 10,477,397 | |
| -1 | -10,477,397 |
Now, we try dividing 10,477,397 by 3:
10,477,397 ÷ 3 = 3,492,465.6667
If the quotient is a whole number, then 3 and 3,492,465.6667 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 | 10,477,397 | |
| -1 | -10,477,397 |
Let's try dividing by 4:
10,477,397 ÷ 4 = 2,619,349.25
If the quotient is a whole number, then 4 and 2,619,349.25 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 | 10,477,397 | |
| -1 | 10,477,397 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 59 | 161 | 413 | 1,103 | 1,357 | 7,721 | 9,499 | 25,369 | 65,077 | 177,583 | 455,539 | 1,496,771 | 10,477,397 |
| -1 | -7 | -23 | -59 | -161 | -413 | -1,103 | -1,357 | -7,721 | -9,499 | -25,369 | -65,077 | -177,583 | -455,539 | -1,496,771 | -10,477,397 |
