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 24,216,325, 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 | 24,216,325 | |
| -1 | -24,216,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,216,325.
Example:
1 x 24,216,325 = 24,216,325
and
-1 x -24,216,325 = 24,216,325
Notice both answers equal 24,216,325
With that explanation out of the way, let's continue. Next, we take the number 24,216,325 and divide it by 2:
24,216,325 ÷ 2 = 12,108,162.5
If the quotient is a whole number, then 2 and 12,108,162.5 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 | 24,216,325 | |
| -1 | -24,216,325 |
Now, we try dividing 24,216,325 by 3:
24,216,325 ÷ 3 = 8,072,108.3333
If the quotient is a whole number, then 3 and 8,072,108.3333 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 | 24,216,325 | |
| -1 | -24,216,325 |
Let's try dividing by 4:
24,216,325 ÷ 4 = 6,054,081.25
If the quotient is a whole number, then 4 and 6,054,081.25 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 | 24,216,325 | |
| -1 | 24,216,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 71 | 175 | 355 | 497 | 1,775 | 1,949 | 2,485 | 9,745 | 12,425 | 13,643 | 48,725 | 68,215 | 138,379 | 341,075 | 691,895 | 968,653 | 3,459,475 | 4,843,265 | 24,216,325 |
| -1 | -5 | -7 | -25 | -35 | -71 | -175 | -355 | -497 | -1,775 | -1,949 | -2,485 | -9,745 | -12,425 | -13,643 | -48,725 | -68,215 | -138,379 | -341,075 | -691,895 | -968,653 | -3,459,475 | -4,843,265 | -24,216,325 |
