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 24,205,525, 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 | 24,205,525 | |
| -1 | -24,205,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,205,525.
Example:
1 x 24,205,525 = 24,205,525
and
-1 x -24,205,525 = 24,205,525
Notice both answers equal 24,205,525
With that explanation out of the way, let's continue. Next, we take the number 24,205,525 and divide it by 2:
24,205,525 ÷ 2 = 12,102,762.5
If the quotient is a whole number, then 2 and 12,102,762.5 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 | 24,205,525 | |
| -1 | -24,205,525 |
Now, we try dividing 24,205,525 by 3:
24,205,525 ÷ 3 = 8,068,508.3333
If the quotient is a whole number, then 3 and 8,068,508.3333 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 | 24,205,525 | |
| -1 | -24,205,525 |
Let's try dividing by 4:
24,205,525 ÷ 4 = 6,051,381.25
If the quotient is a whole number, then 4 and 6,051,381.25 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 | 24,205,525 | |
| -1 | 24,205,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 131 | 389 | 475 | 655 | 1,945 | 2,489 | 3,275 | 7,391 | 9,725 | 12,445 | 36,955 | 50,959 | 62,225 | 184,775 | 254,795 | 968,221 | 1,273,975 | 4,841,105 | 24,205,525 |
| -1 | -5 | -19 | -25 | -95 | -131 | -389 | -475 | -655 | -1,945 | -2,489 | -3,275 | -7,391 | -9,725 | -12,445 | -36,955 | -50,959 | -62,225 | -184,775 | -254,795 | -968,221 | -1,273,975 | -4,841,105 | -24,205,525 |
