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 14,780,347, 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 | 14,780,347 | |
| -1 | -14,780,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,780,347.
Example:
1 x 14,780,347 = 14,780,347
and
-1 x -14,780,347 = 14,780,347
Notice both answers equal 14,780,347
With that explanation out of the way, let's continue. Next, we take the number 14,780,347 and divide it by 2:
14,780,347 ÷ 2 = 7,390,173.5
If the quotient is a whole number, then 2 and 7,390,173.5 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 | 14,780,347 | |
| -1 | -14,780,347 |
Now, we try dividing 14,780,347 by 3:
14,780,347 ÷ 3 = 4,926,782.3333
If the quotient is a whole number, then 3 and 4,926,782.3333 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 | 14,780,347 | |
| -1 | -14,780,347 |
Let's try dividing by 4:
14,780,347 ÷ 4 = 3,695,086.75
If the quotient is a whole number, then 4 and 3,695,086.75 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 | 14,780,347 | |
| -1 | 14,780,347 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 79 | 229 | 817 | 1,501 | 3,397 | 4,351 | 9,847 | 18,091 | 64,543 | 187,093 | 343,729 | 777,913 | 14,780,347 |
| -1 | -19 | -43 | -79 | -229 | -817 | -1,501 | -3,397 | -4,351 | -9,847 | -18,091 | -64,543 | -187,093 | -343,729 | -777,913 | -14,780,347 |
