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 24,213,325, 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 | 24,213,325 | |
| -1 | -24,213,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,213,325.
Example:
1 x 24,213,325 = 24,213,325
and
-1 x -24,213,325 = 24,213,325
Notice both answers equal 24,213,325
With that explanation out of the way, let's continue. Next, we take the number 24,213,325 and divide it by 2:
24,213,325 ÷ 2 = 12,106,662.5
If the quotient is a whole number, then 2 and 12,106,662.5 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 | 24,213,325 | |
| -1 | -24,213,325 |
Now, we try dividing 24,213,325 by 3:
24,213,325 ÷ 3 = 8,071,108.3333
If the quotient is a whole number, then 3 and 8,071,108.3333 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 | 24,213,325 | |
| -1 | -24,213,325 |
Let's try dividing by 4:
24,213,325 ÷ 4 = 6,053,331.25
If the quotient is a whole number, then 4 and 6,053,331.25 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 | 24,213,325 | |
| -1 | 24,213,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 155 | 157 | 199 | 775 | 785 | 995 | 3,925 | 4,867 | 4,975 | 6,169 | 24,335 | 30,845 | 31,243 | 121,675 | 154,225 | 156,215 | 781,075 | 968,533 | 4,842,665 | 24,213,325 |
| -1 | -5 | -25 | -31 | -155 | -157 | -199 | -775 | -785 | -995 | -3,925 | -4,867 | -4,975 | -6,169 | -24,335 | -30,845 | -31,243 | -121,675 | -154,225 | -156,215 | -781,075 | -968,533 | -4,842,665 | -24,213,325 |
