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 498,545, 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 | 498,545 | |
-1 | -498,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 498,545.
Example:
1 x 498,545 = 498,545
and
-1 x -498,545 = 498,545
Notice both answers equal 498,545
With that explanation out of the way, let's continue. Next, we take the number 498,545 and divide it by 2:
498,545 ÷ 2 = 249,272.5
If the quotient is a whole number, then 2 and 249,272.5 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 | 498,545 | |
-1 | -498,545 |
Now, we try dividing 498,545 by 3:
498,545 ÷ 3 = 166,181.6667
If the quotient is a whole number, then 3 and 166,181.6667 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 | 498,545 | |
-1 | -498,545 |
Let's try dividing by 4:
498,545 ÷ 4 = 124,636.25
If the quotient is a whole number, then 4 and 124,636.25 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 | 498,545 | |
-1 | 498,545 |
If you did it right, you will end up with this table:
1 | 5 | 99,709 | 498,545 |
-1 | -5 | -99,709 | -498,545 |
