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 24,650,425, 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 | 24,650,425 | |
| -1 | -24,650,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,650,425.
Example:
1 x 24,650,425 = 24,650,425
and
-1 x -24,650,425 = 24,650,425
Notice both answers equal 24,650,425
With that explanation out of the way, let's continue. Next, we take the number 24,650,425 and divide it by 2:
24,650,425 ÷ 2 = 12,325,212.5
If the quotient is a whole number, then 2 and 12,325,212.5 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 | 24,650,425 | |
| -1 | -24,650,425 |
Now, we try dividing 24,650,425 by 3:
24,650,425 ÷ 3 = 8,216,808.3333
If the quotient is a whole number, then 3 and 8,216,808.3333 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 | 24,650,425 | |
| -1 | -24,650,425 |
Let's try dividing by 4:
24,650,425 ÷ 4 = 6,162,606.25
If the quotient is a whole number, then 4 and 6,162,606.25 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 | 24,650,425 | |
| -1 | 24,650,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 31 | 85 | 155 | 425 | 527 | 775 | 1,871 | 2,635 | 9,355 | 13,175 | 31,807 | 46,775 | 58,001 | 159,035 | 290,005 | 795,175 | 986,017 | 1,450,025 | 4,930,085 | 24,650,425 |
| -1 | -5 | -17 | -25 | -31 | -85 | -155 | -425 | -527 | -775 | -1,871 | -2,635 | -9,355 | -13,175 | -31,807 | -46,775 | -58,001 | -159,035 | -290,005 | -795,175 | -986,017 | -1,450,025 | -4,930,085 | -24,650,425 |
