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 13,849,297, 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 | 13,849,297 | |
| -1 | -13,849,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,849,297.
Example:
1 x 13,849,297 = 13,849,297
and
-1 x -13,849,297 = 13,849,297
Notice both answers equal 13,849,297
With that explanation out of the way, let's continue. Next, we take the number 13,849,297 and divide it by 2:
13,849,297 ÷ 2 = 6,924,648.5
If the quotient is a whole number, then 2 and 6,924,648.5 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 | 13,849,297 | |
| -1 | -13,849,297 |
Now, we try dividing 13,849,297 by 3:
13,849,297 ÷ 3 = 4,616,432.3333
If the quotient is a whole number, then 3 and 4,616,432.3333 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 | 13,849,297 | |
| -1 | -13,849,297 |
Let's try dividing by 4:
13,849,297 ÷ 4 = 3,462,324.25
If the quotient is a whole number, then 4 and 3,462,324.25 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 | 13,849,297 | |
| -1 | 13,849,297 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 83 | 121 | 197 | 581 | 847 | 913 | 1,379 | 2,167 | 6,391 | 10,043 | 15,169 | 16,351 | 23,837 | 70,301 | 114,457 | 166,859 | 179,861 | 1,259,027 | 1,978,471 | 13,849,297 |
| -1 | -7 | -11 | -77 | -83 | -121 | -197 | -581 | -847 | -913 | -1,379 | -2,167 | -6,391 | -10,043 | -15,169 | -16,351 | -23,837 | -70,301 | -114,457 | -166,859 | -179,861 | -1,259,027 | -1,978,471 | -13,849,297 |
