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 24,727,235, 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 | 24,727,235 | |
| -1 | -24,727,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,727,235.
Example:
1 x 24,727,235 = 24,727,235
and
-1 x -24,727,235 = 24,727,235
Notice both answers equal 24,727,235
With that explanation out of the way, let's continue. Next, we take the number 24,727,235 and divide it by 2:
24,727,235 ÷ 2 = 12,363,617.5
If the quotient is a whole number, then 2 and 12,363,617.5 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 | 24,727,235 | |
| -1 | -24,727,235 |
Now, we try dividing 24,727,235 by 3:
24,727,235 ÷ 3 = 8,242,411.6667
If the quotient is a whole number, then 3 and 8,242,411.6667 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 | 24,727,235 | |
| -1 | -24,727,235 |
Let's try dividing by 4:
24,727,235 ÷ 4 = 6,181,808.75
If the quotient is a whole number, then 4 and 6,181,808.75 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 | 24,727,235 | |
| -1 | 24,727,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 169 | 845 | 2,197 | 2,251 | 10,985 | 11,255 | 29,263 | 146,315 | 380,419 | 1,902,095 | 4,945,447 | 24,727,235 |
| -1 | -5 | -13 | -65 | -169 | -845 | -2,197 | -2,251 | -10,985 | -11,255 | -29,263 | -146,315 | -380,419 | -1,902,095 | -4,945,447 | -24,727,235 |
