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 351,839, 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 | 351,839 | |
-1 | -351,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,839.
Example:
1 x 351,839 = 351,839
and
-1 x -351,839 = 351,839
Notice both answers equal 351,839
With that explanation out of the way, let's continue. Next, we take the number 351,839 and divide it by 2:
351,839 ÷ 2 = 175,919.5
If the quotient is a whole number, then 2 and 175,919.5 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 | 351,839 | |
-1 | -351,839 |
Now, we try dividing 351,839 by 3:
351,839 ÷ 3 = 117,279.6667
If the quotient is a whole number, then 3 and 117,279.6667 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 | 351,839 | |
-1 | -351,839 |
Let's try dividing by 4:
351,839 ÷ 4 = 87,959.75
If the quotient is a whole number, then 4 and 87,959.75 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 | 351,839 | |
-1 | 351,839 |
If you did it right, you will end up with this table:
1 | 193 | 1,823 | 351,839 |
-1 | -193 | -1,823 | -351,839 |
