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 24,572,165, 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 | 24,572,165 | |
| -1 | -24,572,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,572,165.
Example:
1 x 24,572,165 = 24,572,165
and
-1 x -24,572,165 = 24,572,165
Notice both answers equal 24,572,165
With that explanation out of the way, let's continue. Next, we take the number 24,572,165 and divide it by 2:
24,572,165 ÷ 2 = 12,286,082.5
If the quotient is a whole number, then 2 and 12,286,082.5 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 | 24,572,165 | |
| -1 | -24,572,165 |
Now, we try dividing 24,572,165 by 3:
24,572,165 ÷ 3 = 8,190,721.6667
If the quotient is a whole number, then 3 and 8,190,721.6667 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 | 24,572,165 | |
| -1 | -24,572,165 |
Let's try dividing by 4:
24,572,165 ÷ 4 = 6,143,041.25
If the quotient is a whole number, then 4 and 6,143,041.25 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 | 24,572,165 | |
| -1 | 24,572,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 73 | 115 | 365 | 1,679 | 2,927 | 8,395 | 14,635 | 67,321 | 213,671 | 336,605 | 1,068,355 | 4,914,433 | 24,572,165 |
| -1 | -5 | -23 | -73 | -115 | -365 | -1,679 | -2,927 | -8,395 | -14,635 | -67,321 | -213,671 | -336,605 | -1,068,355 | -4,914,433 | -24,572,165 |
