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 403,963, 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 | 403,963 | |
-1 | -403,963 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,963.
Example:
1 x 403,963 = 403,963
and
-1 x -403,963 = 403,963
Notice both answers equal 403,963
With that explanation out of the way, let's continue. Next, we take the number 403,963 and divide it by 2:
403,963 ÷ 2 = 201,981.5
If the quotient is a whole number, then 2 and 201,981.5 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 | 403,963 | |
-1 | -403,963 |
Now, we try dividing 403,963 by 3:
403,963 ÷ 3 = 134,654.3333
If the quotient is a whole number, then 3 and 134,654.3333 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 | 403,963 | |
-1 | -403,963 |
Let's try dividing by 4:
403,963 ÷ 4 = 100,990.75
If the quotient is a whole number, then 4 and 100,990.75 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 | 403,963 | |
-1 | 403,963 |
If you did it right, you will end up with this table:
1 | 7 | 57,709 | 403,963 |
-1 | -7 | -57,709 | -403,963 |
