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 24,903,053, 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 | 24,903,053 | |
| -1 | -24,903,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,903,053.
Example:
1 x 24,903,053 = 24,903,053
and
-1 x -24,903,053 = 24,903,053
Notice both answers equal 24,903,053
With that explanation out of the way, let's continue. Next, we take the number 24,903,053 and divide it by 2:
24,903,053 ÷ 2 = 12,451,526.5
If the quotient is a whole number, then 2 and 12,451,526.5 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 | 24,903,053 | |
| -1 | -24,903,053 |
Now, we try dividing 24,903,053 by 3:
24,903,053 ÷ 3 = 8,301,017.6667
If the quotient is a whole number, then 3 and 8,301,017.6667 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 | 24,903,053 | |
| -1 | -24,903,053 |
Let's try dividing by 4:
24,903,053 ÷ 4 = 6,225,763.25
If the quotient is a whole number, then 4 and 6,225,763.25 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 | 24,903,053 | |
| -1 | 24,903,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 113 | 133 | 791 | 1,657 | 2,147 | 11,599 | 15,029 | 31,483 | 187,241 | 220,381 | 1,310,687 | 3,557,579 | 24,903,053 |
| -1 | -7 | -19 | -113 | -133 | -791 | -1,657 | -2,147 | -11,599 | -15,029 | -31,483 | -187,241 | -220,381 | -1,310,687 | -3,557,579 | -24,903,053 |
