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 554,216,453, 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 | 554,216,453 | |
| -1 | -554,216,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,216,453.
Example:
1 x 554,216,453 = 554,216,453
and
-1 x -554,216,453 = 554,216,453
Notice both answers equal 554,216,453
With that explanation out of the way, let's continue. Next, we take the number 554,216,453 and divide it by 2:
554,216,453 ÷ 2 = 277,108,226.5
If the quotient is a whole number, then 2 and 277,108,226.5 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 | 554,216,453 | |
| -1 | -554,216,453 |
Now, we try dividing 554,216,453 by 3:
554,216,453 ÷ 3 = 184,738,817.6667
If the quotient is a whole number, then 3 and 184,738,817.6667 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 | 554,216,453 | |
| -1 | -554,216,453 |
Let's try dividing by 4:
554,216,453 ÷ 4 = 138,554,113.25
If the quotient is a whole number, then 4 and 138,554,113.25 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 | 554,216,453 | |
| -1 | 554,216,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 467 | 3,269 | 8,873 | 8,923 | 62,111 | 62,461 | 169,537 | 1,186,759 | 4,167,041 | 29,169,287 | 79,173,779 | 554,216,453 |
| -1 | -7 | -19 | -133 | -467 | -3,269 | -8,873 | -8,923 | -62,111 | -62,461 | -169,537 | -1,186,759 | -4,167,041 | -29,169,287 | -79,173,779 | -554,216,453 |
