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 437,887, 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 | 437,887 | |
-1 | -437,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 437,887.
Example:
1 x 437,887 = 437,887
and
-1 x -437,887 = 437,887
Notice both answers equal 437,887
With that explanation out of the way, let's continue. Next, we take the number 437,887 and divide it by 2:
437,887 ÷ 2 = 218,943.5
If the quotient is a whole number, then 2 and 218,943.5 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 | 437,887 | |
-1 | -437,887 |
Now, we try dividing 437,887 by 3:
437,887 ÷ 3 = 145,962.3333
If the quotient is a whole number, then 3 and 145,962.3333 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 | 437,887 | |
-1 | -437,887 |
Let's try dividing by 4:
437,887 ÷ 4 = 109,471.75
If the quotient is a whole number, then 4 and 109,471.75 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 | 437,887 | |
-1 | 437,887 |
If you did it right, you will end up with this table:
1 | 313 | 1,399 | 437,887 |
-1 | -313 | -1,399 | -437,887 |
