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 100,232,425, 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 | 100,232,425 | |
| -1 | -100,232,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,232,425.
Example:
1 x 100,232,425 = 100,232,425
and
-1 x -100,232,425 = 100,232,425
Notice both answers equal 100,232,425
With that explanation out of the way, let's continue. Next, we take the number 100,232,425 and divide it by 2:
100,232,425 ÷ 2 = 50,116,212.5
If the quotient is a whole number, then 2 and 50,116,212.5 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 | 100,232,425 | |
| -1 | -100,232,425 |
Now, we try dividing 100,232,425 by 3:
100,232,425 ÷ 3 = 33,410,808.3333
If the quotient is a whole number, then 3 and 33,410,808.3333 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 | 100,232,425 | |
| -1 | -100,232,425 |
Let's try dividing by 4:
100,232,425 ÷ 4 = 25,058,106.25
If the quotient is a whole number, then 4 and 25,058,106.25 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 | 100,232,425 | |
| -1 | 100,232,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 289 | 425 | 1,445 | 7,225 | 13,873 | 69,365 | 235,841 | 346,825 | 1,179,205 | 4,009,297 | 5,896,025 | 20,046,485 | 100,232,425 |
| -1 | -5 | -17 | -25 | -85 | -289 | -425 | -1,445 | -7,225 | -13,873 | -69,365 | -235,841 | -346,825 | -1,179,205 | -4,009,297 | -5,896,025 | -20,046,485 | -100,232,425 |
