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 14,245,777, 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 | 14,245,777 | |
| -1 | -14,245,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,245,777.
Example:
1 x 14,245,777 = 14,245,777
and
-1 x -14,245,777 = 14,245,777
Notice both answers equal 14,245,777
With that explanation out of the way, let's continue. Next, we take the number 14,245,777 and divide it by 2:
14,245,777 ÷ 2 = 7,122,888.5
If the quotient is a whole number, then 2 and 7,122,888.5 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 | 14,245,777 | |
| -1 | -14,245,777 |
Now, we try dividing 14,245,777 by 3:
14,245,777 ÷ 3 = 4,748,592.3333
If the quotient is a whole number, then 3 and 4,748,592.3333 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 | 14,245,777 | |
| -1 | -14,245,777 |
Let's try dividing by 4:
14,245,777 ÷ 4 = 3,561,444.25
If the quotient is a whole number, then 4 and 3,561,444.25 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 | 14,245,777 | |
| -1 | 14,245,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 3,367 | 4,231 | 29,617 | 55,003 | 156,547 | 385,021 | 1,095,829 | 2,035,111 | 14,245,777 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -3,367 | -4,231 | -29,617 | -55,003 | -156,547 | -385,021 | -1,095,829 | -2,035,111 | -14,245,777 |
