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 554,046,451, 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 | 554,046,451 | |
| -1 | -554,046,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,046,451.
Example:
1 x 554,046,451 = 554,046,451
and
-1 x -554,046,451 = 554,046,451
Notice both answers equal 554,046,451
With that explanation out of the way, let's continue. Next, we take the number 554,046,451 and divide it by 2:
554,046,451 ÷ 2 = 277,023,225.5
If the quotient is a whole number, then 2 and 277,023,225.5 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 | 554,046,451 | |
| -1 | -554,046,451 |
Now, we try dividing 554,046,451 by 3:
554,046,451 ÷ 3 = 184,682,150.3333
If the quotient is a whole number, then 3 and 184,682,150.3333 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 | 554,046,451 | |
| -1 | -554,046,451 |
Let's try dividing by 4:
554,046,451 ÷ 4 = 138,511,612.75
If the quotient is a whole number, then 4 and 138,511,612.75 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 | 554,046,451 | |
| -1 | 554,046,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 193 | 397 | 1,033 | 1,351 | 2,779 | 7,231 | 76,621 | 199,369 | 410,101 | 536,347 | 1,395,583 | 2,870,707 | 79,149,493 | 554,046,451 |
| -1 | -7 | -193 | -397 | -1,033 | -1,351 | -2,779 | -7,231 | -76,621 | -199,369 | -410,101 | -536,347 | -1,395,583 | -2,870,707 | -79,149,493 | -554,046,451 |
