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 24,040,345, 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 | 24,040,345 | |
| -1 | -24,040,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,040,345.
Example:
1 x 24,040,345 = 24,040,345
and
-1 x -24,040,345 = 24,040,345
Notice both answers equal 24,040,345
With that explanation out of the way, let's continue. Next, we take the number 24,040,345 and divide it by 2:
24,040,345 ÷ 2 = 12,020,172.5
If the quotient is a whole number, then 2 and 12,020,172.5 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 | 24,040,345 | |
| -1 | -24,040,345 |
Now, we try dividing 24,040,345 by 3:
24,040,345 ÷ 3 = 8,013,448.3333
If the quotient is a whole number, then 3 and 8,013,448.3333 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 | 24,040,345 | |
| -1 | -24,040,345 |
Let's try dividing by 4:
24,040,345 ÷ 4 = 6,010,086.25
If the quotient is a whole number, then 4 and 6,010,086.25 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 | 24,040,345 | |
| -1 | 24,040,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 22,157 | 110,785 | 155,099 | 686,867 | 775,495 | 3,434,335 | 4,808,069 | 24,040,345 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -22,157 | -110,785 | -155,099 | -686,867 | -775,495 | -3,434,335 | -4,808,069 | -24,040,345 |
