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 10,347,649, 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 | 10,347,649 | |
| -1 | -10,347,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,347,649.
Example:
1 x 10,347,649 = 10,347,649
and
-1 x -10,347,649 = 10,347,649
Notice both answers equal 10,347,649
With that explanation out of the way, let's continue. Next, we take the number 10,347,649 and divide it by 2:
10,347,649 ÷ 2 = 5,173,824.5
If the quotient is a whole number, then 2 and 5,173,824.5 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 | 10,347,649 | |
| -1 | -10,347,649 |
Now, we try dividing 10,347,649 by 3:
10,347,649 ÷ 3 = 3,449,216.3333
If the quotient is a whole number, then 3 and 3,449,216.3333 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 | 10,347,649 | |
| -1 | -10,347,649 |
Let's try dividing by 4:
10,347,649 ÷ 4 = 2,586,912.25
If the quotient is a whole number, then 4 and 2,586,912.25 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 | 10,347,649 | |
| -1 | 10,347,649 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 107 | 173 | 559 | 1,391 | 2,249 | 4,601 | 7,439 | 18,511 | 59,813 | 96,707 | 240,643 | 795,973 | 10,347,649 |
| -1 | -13 | -43 | -107 | -173 | -559 | -1,391 | -2,249 | -4,601 | -7,439 | -18,511 | -59,813 | -96,707 | -240,643 | -795,973 | -10,347,649 |
