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 28,232,587, 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 | 28,232,587 | |
-1 | -28,232,587 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,232,587.
Example:
1 x 28,232,587 = 28,232,587
and
-1 x -28,232,587 = 28,232,587
Notice both answers equal 28,232,587
With that explanation out of the way, let's continue. Next, we take the number 28,232,587 and divide it by 2:
28,232,587 ÷ 2 = 14,116,293.5
If the quotient is a whole number, then 2 and 14,116,293.5 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 | 28,232,587 | |
-1 | -28,232,587 |
Now, we try dividing 28,232,587 by 3:
28,232,587 ÷ 3 = 9,410,862.3333
If the quotient is a whole number, then 3 and 9,410,862.3333 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 | 28,232,587 | |
-1 | -28,232,587 |
Let's try dividing by 4:
28,232,587 ÷ 4 = 7,058,146.75
If the quotient is a whole number, then 4 and 7,058,146.75 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 | 28,232,587 | |
-1 | 28,232,587 |
If you did it right, you will end up with this table:
1 | 353 | 79,979 | 28,232,587 |
-1 | -353 | -79,979 | -28,232,587 |
