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 12,467,735, 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 | 12,467,735 | |
| -1 | -12,467,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,467,735.
Example:
1 x 12,467,735 = 12,467,735
and
-1 x -12,467,735 = 12,467,735
Notice both answers equal 12,467,735
With that explanation out of the way, let's continue. Next, we take the number 12,467,735 and divide it by 2:
12,467,735 ÷ 2 = 6,233,867.5
If the quotient is a whole number, then 2 and 6,233,867.5 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 | 12,467,735 | |
| -1 | -12,467,735 |
Now, we try dividing 12,467,735 by 3:
12,467,735 ÷ 3 = 4,155,911.6667
If the quotient is a whole number, then 3 and 4,155,911.6667 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 | 12,467,735 | |
| -1 | -12,467,735 |
Let's try dividing by 4:
12,467,735 ÷ 4 = 3,116,933.75
If the quotient is a whole number, then 4 and 3,116,933.75 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 | 12,467,735 | |
| -1 | 12,467,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 11,491 | 57,455 | 80,437 | 356,221 | 402,185 | 1,781,105 | 2,493,547 | 12,467,735 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -11,491 | -57,455 | -80,437 | -356,221 | -402,185 | -1,781,105 | -2,493,547 | -12,467,735 |
