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 12,346,477, 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 | 12,346,477 | |
| -1 | -12,346,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,346,477.
Example:
1 x 12,346,477 = 12,346,477
and
-1 x -12,346,477 = 12,346,477
Notice both answers equal 12,346,477
With that explanation out of the way, let's continue. Next, we take the number 12,346,477 and divide it by 2:
12,346,477 ÷ 2 = 6,173,238.5
If the quotient is a whole number, then 2 and 6,173,238.5 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 | 12,346,477 | |
| -1 | -12,346,477 |
Now, we try dividing 12,346,477 by 3:
12,346,477 ÷ 3 = 4,115,492.3333
If the quotient is a whole number, then 3 and 4,115,492.3333 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 | 12,346,477 | |
| -1 | -12,346,477 |
Let's try dividing by 4:
12,346,477 ÷ 4 = 3,086,619.25
If the quotient is a whole number, then 4 and 3,086,619.25 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 | 12,346,477 | |
| -1 | 12,346,477 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 47 | 121 | 143 | 167 | 517 | 611 | 1,573 | 1,837 | 2,171 | 5,687 | 6,721 | 7,849 | 20,207 | 23,881 | 73,931 | 86,339 | 102,037 | 262,691 | 949,729 | 1,122,407 | 12,346,477 |
| -1 | -11 | -13 | -47 | -121 | -143 | -167 | -517 | -611 | -1,573 | -1,837 | -2,171 | -5,687 | -6,721 | -7,849 | -20,207 | -23,881 | -73,931 | -86,339 | -102,037 | -262,691 | -949,729 | -1,122,407 | -12,346,477 |
