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 24,949,273, 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 | 24,949,273 | |
| -1 | -24,949,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,949,273.
Example:
1 x 24,949,273 = 24,949,273
and
-1 x -24,949,273 = 24,949,273
Notice both answers equal 24,949,273
With that explanation out of the way, let's continue. Next, we take the number 24,949,273 and divide it by 2:
24,949,273 ÷ 2 = 12,474,636.5
If the quotient is a whole number, then 2 and 12,474,636.5 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 | 24,949,273 | |
| -1 | -24,949,273 |
Now, we try dividing 24,949,273 by 3:
24,949,273 ÷ 3 = 8,316,424.3333
If the quotient is a whole number, then 3 and 8,316,424.3333 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 | 24,949,273 | |
| -1 | -24,949,273 |
Let's try dividing by 4:
24,949,273 ÷ 4 = 6,237,318.25
If the quotient is a whole number, then 4 and 6,237,318.25 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 | 24,949,273 | |
| -1 | 24,949,273 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 97 | 211 | 1,219 | 2,231 | 4,853 | 5,141 | 11,183 | 20,467 | 118,243 | 257,209 | 470,741 | 1,084,751 | 24,949,273 |
| -1 | -23 | -53 | -97 | -211 | -1,219 | -2,231 | -4,853 | -5,141 | -11,183 | -20,467 | -118,243 | -257,209 | -470,741 | -1,084,751 | -24,949,273 |
