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 14,278,649, 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 | 14,278,649 | |
| -1 | -14,278,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,278,649.
Example:
1 x 14,278,649 = 14,278,649
and
-1 x -14,278,649 = 14,278,649
Notice both answers equal 14,278,649
With that explanation out of the way, let's continue. Next, we take the number 14,278,649 and divide it by 2:
14,278,649 ÷ 2 = 7,139,324.5
If the quotient is a whole number, then 2 and 7,139,324.5 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 | 14,278,649 | |
| -1 | -14,278,649 |
Now, we try dividing 14,278,649 by 3:
14,278,649 ÷ 3 = 4,759,549.6667
If the quotient is a whole number, then 3 and 4,759,549.6667 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 | 14,278,649 | |
| -1 | -14,278,649 |
Let's try dividing by 4:
14,278,649 ÷ 4 = 3,569,662.25
If the quotient is a whole number, then 4 and 3,569,662.25 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 | 14,278,649 | |
| -1 | 14,278,649 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 59 | 77 | 413 | 449 | 539 | 649 | 2,891 | 3,143 | 4,543 | 4,939 | 22,001 | 26,491 | 31,801 | 34,573 | 185,437 | 242,011 | 291,401 | 1,298,059 | 2,039,807 | 14,278,649 |
| -1 | -7 | -11 | -49 | -59 | -77 | -413 | -449 | -539 | -649 | -2,891 | -3,143 | -4,543 | -4,939 | -22,001 | -26,491 | -31,801 | -34,573 | -185,437 | -242,011 | -291,401 | -1,298,059 | -2,039,807 | -14,278,649 |
