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 24,653,525, 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 | 24,653,525 | |
| -1 | -24,653,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,653,525.
Example:
1 x 24,653,525 = 24,653,525
and
-1 x -24,653,525 = 24,653,525
Notice both answers equal 24,653,525
With that explanation out of the way, let's continue. Next, we take the number 24,653,525 and divide it by 2:
24,653,525 ÷ 2 = 12,326,762.5
If the quotient is a whole number, then 2 and 12,326,762.5 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 | 24,653,525 | |
| -1 | -24,653,525 |
Now, we try dividing 24,653,525 by 3:
24,653,525 ÷ 3 = 8,217,841.6667
If the quotient is a whole number, then 3 and 8,217,841.6667 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 | 24,653,525 | |
| -1 | -24,653,525 |
Let's try dividing by 4:
24,653,525 ÷ 4 = 6,163,381.25
If the quotient is a whole number, then 4 and 6,163,381.25 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 | 24,653,525 | |
| -1 | 24,653,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 31 | 65 | 155 | 325 | 403 | 775 | 2,015 | 2,447 | 10,075 | 12,235 | 31,811 | 61,175 | 75,857 | 159,055 | 379,285 | 795,275 | 986,141 | 1,896,425 | 4,930,705 | 24,653,525 |
| -1 | -5 | -13 | -25 | -31 | -65 | -155 | -325 | -403 | -775 | -2,015 | -2,447 | -10,075 | -12,235 | -31,811 | -61,175 | -75,857 | -159,055 | -379,285 | -795,275 | -986,141 | -1,896,425 | -4,930,705 | -24,653,525 |
