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 557,363,371, 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 | 557,363,371 | |
-1 | -557,363,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 557,363,371.
Example:
1 x 557,363,371 = 557,363,371
and
-1 x -557,363,371 = 557,363,371
Notice both answers equal 557,363,371
With that explanation out of the way, let's continue. Next, we take the number 557,363,371 and divide it by 2:
557,363,371 ÷ 2 = 278,681,685.5
If the quotient is a whole number, then 2 and 278,681,685.5 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 | 557,363,371 | |
-1 | -557,363,371 |
Now, we try dividing 557,363,371 by 3:
557,363,371 ÷ 3 = 185,787,790.3333
If the quotient is a whole number, then 3 and 185,787,790.3333 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 | 557,363,371 | |
-1 | -557,363,371 |
Let's try dividing by 4:
557,363,371 ÷ 4 = 139,340,842.75
If the quotient is a whole number, then 4 and 139,340,842.75 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 | 557,363,371 | |
-1 | 557,363,371 |
If you did it right, you will end up with this table:
1 | 1,471 | 378,901 | 557,363,371 |
-1 | -1,471 | -378,901 | -557,363,371 |
