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 455,304,553, 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 | 455,304,553 | |
| -1 | -455,304,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,304,553.
Example:
1 x 455,304,553 = 455,304,553
and
-1 x -455,304,553 = 455,304,553
Notice both answers equal 455,304,553
With that explanation out of the way, let's continue. Next, we take the number 455,304,553 and divide it by 2:
455,304,553 ÷ 2 = 227,652,276.5
If the quotient is a whole number, then 2 and 227,652,276.5 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 | 455,304,553 | |
| -1 | -455,304,553 |
Now, we try dividing 455,304,553 by 3:
455,304,553 ÷ 3 = 151,768,184.3333
If the quotient is a whole number, then 3 and 151,768,184.3333 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 | 455,304,553 | |
| -1 | -455,304,553 |
Let's try dividing by 4:
455,304,553 ÷ 4 = 113,826,138.25
If the quotient is a whole number, then 4 and 113,826,138.25 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 | 455,304,553 | |
| -1 | 455,304,553 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 157 | 319 | 1,727 | 4,553 | 9,091 | 50,083 | 100,001 | 263,639 | 1,427,287 | 2,900,029 | 15,700,157 | 41,391,323 | 455,304,553 |
| -1 | -11 | -29 | -157 | -319 | -1,727 | -4,553 | -9,091 | -50,083 | -100,001 | -263,639 | -1,427,287 | -2,900,029 | -15,700,157 | -41,391,323 | -455,304,553 |
