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 24,506,125, 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 | 24,506,125 | |
| -1 | -24,506,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,506,125.
Example:
1 x 24,506,125 = 24,506,125
and
-1 x -24,506,125 = 24,506,125
Notice both answers equal 24,506,125
With that explanation out of the way, let's continue. Next, we take the number 24,506,125 and divide it by 2:
24,506,125 ÷ 2 = 12,253,062.5
If the quotient is a whole number, then 2 and 12,253,062.5 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 | 24,506,125 | |
| -1 | -24,506,125 |
Now, we try dividing 24,506,125 by 3:
24,506,125 ÷ 3 = 8,168,708.3333
If the quotient is a whole number, then 3 and 8,168,708.3333 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 | 24,506,125 | |
| -1 | -24,506,125 |
Let's try dividing by 4:
24,506,125 ÷ 4 = 6,126,531.25
If the quotient is a whole number, then 4 and 6,126,531.25 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 | 24,506,125 | |
| -1 | 24,506,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 125 | 175 | 245 | 875 | 1,225 | 4,001 | 6,125 | 20,005 | 28,007 | 100,025 | 140,035 | 196,049 | 500,125 | 700,175 | 980,245 | 3,500,875 | 4,901,225 | 24,506,125 |
| -1 | -5 | -7 | -25 | -35 | -49 | -125 | -175 | -245 | -875 | -1,225 | -4,001 | -6,125 | -20,005 | -28,007 | -100,025 | -140,035 | -196,049 | -500,125 | -700,175 | -980,245 | -3,500,875 | -4,901,225 | -24,506,125 |
