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 452,515,153, 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 | 452,515,153 | |
| -1 | -452,515,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 452,515,153.
Example:
1 x 452,515,153 = 452,515,153
and
-1 x -452,515,153 = 452,515,153
Notice both answers equal 452,515,153
With that explanation out of the way, let's continue. Next, we take the number 452,515,153 and divide it by 2:
452,515,153 ÷ 2 = 226,257,576.5
If the quotient is a whole number, then 2 and 226,257,576.5 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 | 452,515,153 | |
| -1 | -452,515,153 |
Now, we try dividing 452,515,153 by 3:
452,515,153 ÷ 3 = 150,838,384.3333
If the quotient is a whole number, then 3 and 150,838,384.3333 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 | 452,515,153 | |
| -1 | -452,515,153 |
Let's try dividing by 4:
452,515,153 ÷ 4 = 113,128,788.25
If the quotient is a whole number, then 4 and 113,128,788.25 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 | 452,515,153 | |
| -1 | 452,515,153 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 103 | 589 | 1,957 | 3,193 | 7,459 | 60,667 | 141,721 | 231,229 | 768,277 | 4,393,351 | 14,597,263 | 23,816,587 | 452,515,153 |
| -1 | -19 | -31 | -103 | -589 | -1,957 | -3,193 | -7,459 | -60,667 | -141,721 | -231,229 | -768,277 | -4,393,351 | -14,597,263 | -23,816,587 | -452,515,153 |
