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 158,447, 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 | 158,447 | |
-1 | -158,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 158,447.
Example:
1 x 158,447 = 158,447
and
-1 x -158,447 = 158,447
Notice both answers equal 158,447
With that explanation out of the way, let's continue. Next, we take the number 158,447 and divide it by 2:
158,447 ÷ 2 = 79,223.5
If the quotient is a whole number, then 2 and 79,223.5 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 | 158,447 | |
-1 | -158,447 |
Now, we try dividing 158,447 by 3:
158,447 ÷ 3 = 52,815.6667
If the quotient is a whole number, then 3 and 52,815.6667 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 | 158,447 | |
-1 | -158,447 |
Let's try dividing by 4:
158,447 ÷ 4 = 39,611.75
If the quotient is a whole number, then 4 and 39,611.75 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 | 158,447 | |
-1 | 158,447 |
If you did it right, you will end up with this table:
1 | 23 | 83 | 1,909 | 6,889 | 158,447 |
-1 | -23 | -83 | -1,909 | -6,889 | -158,447 |
