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 553,641,443, 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 | 553,641,443 | |
-1 | -553,641,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,641,443.
Example:
1 x 553,641,443 = 553,641,443
and
-1 x -553,641,443 = 553,641,443
Notice both answers equal 553,641,443
With that explanation out of the way, let's continue. Next, we take the number 553,641,443 and divide it by 2:
553,641,443 ÷ 2 = 276,820,721.5
If the quotient is a whole number, then 2 and 276,820,721.5 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 | 553,641,443 | |
-1 | -553,641,443 |
Now, we try dividing 553,641,443 by 3:
553,641,443 ÷ 3 = 184,547,147.6667
If the quotient is a whole number, then 3 and 184,547,147.6667 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 | 553,641,443 | |
-1 | -553,641,443 |
Let's try dividing by 4:
553,641,443 ÷ 4 = 138,410,360.75
If the quotient is a whole number, then 4 and 138,410,360.75 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 | 553,641,443 | |
-1 | 553,641,443 |
If you did it right, you will end up with this table:
1 | 1,283 | 431,521 | 553,641,443 |
-1 | -1,283 | -431,521 | -553,641,443 |
