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 24,572,485, 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 | 24,572,485 | |
| -1 | -24,572,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,572,485.
Example:
1 x 24,572,485 = 24,572,485
and
-1 x -24,572,485 = 24,572,485
Notice both answers equal 24,572,485
With that explanation out of the way, let's continue. Next, we take the number 24,572,485 and divide it by 2:
24,572,485 ÷ 2 = 12,286,242.5
If the quotient is a whole number, then 2 and 12,286,242.5 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 | 24,572,485 | |
| -1 | -24,572,485 |
Now, we try dividing 24,572,485 by 3:
24,572,485 ÷ 3 = 8,190,828.3333
If the quotient is a whole number, then 3 and 8,190,828.3333 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 | 24,572,485 | |
| -1 | -24,572,485 |
Let's try dividing by 4:
24,572,485 ÷ 4 = 6,143,121.25
If the quotient is a whole number, then 4 and 6,143,121.25 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 | 24,572,485 | |
| -1 | 24,572,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 367 | 1,835 | 1,913 | 2,569 | 9,565 | 12,845 | 13,391 | 66,955 | 702,071 | 3,510,355 | 4,914,497 | 24,572,485 |
| -1 | -5 | -7 | -35 | -367 | -1,835 | -1,913 | -2,569 | -9,565 | -12,845 | -13,391 | -66,955 | -702,071 | -3,510,355 | -4,914,497 | -24,572,485 |
