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 356,393, 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 | 356,393 | |
-1 | -356,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,393.
Example:
1 x 356,393 = 356,393
and
-1 x -356,393 = 356,393
Notice both answers equal 356,393
With that explanation out of the way, let's continue. Next, we take the number 356,393 and divide it by 2:
356,393 ÷ 2 = 178,196.5
If the quotient is a whole number, then 2 and 178,196.5 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 | 356,393 | |
-1 | -356,393 |
Now, we try dividing 356,393 by 3:
356,393 ÷ 3 = 118,797.6667
If the quotient is a whole number, then 3 and 118,797.6667 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 | 356,393 | |
-1 | -356,393 |
Let's try dividing by 4:
356,393 ÷ 4 = 89,098.25
If the quotient is a whole number, then 4 and 89,098.25 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 | 356,393 | |
-1 | 356,393 |
If you did it right, you will end up with this table:
1 | 593 | 601 | 356,393 |
-1 | -593 | -601 | -356,393 |
