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 451,013,305, 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 | 451,013,305 | |
| -1 | -451,013,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,013,305.
Example:
1 x 451,013,305 = 451,013,305
and
-1 x -451,013,305 = 451,013,305
Notice both answers equal 451,013,305
With that explanation out of the way, let's continue. Next, we take the number 451,013,305 and divide it by 2:
451,013,305 ÷ 2 = 225,506,652.5
If the quotient is a whole number, then 2 and 225,506,652.5 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 | 451,013,305 | |
| -1 | -451,013,305 |
Now, we try dividing 451,013,305 by 3:
451,013,305 ÷ 3 = 150,337,768.3333
If the quotient is a whole number, then 3 and 150,337,768.3333 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 | 451,013,305 | |
| -1 | -451,013,305 |
Let's try dividing by 4:
451,013,305 ÷ 4 = 112,753,326.25
If the quotient is a whole number, then 4 and 112,753,326.25 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 | 451,013,305 | |
| -1 | 451,013,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 829 | 2,053 | 4,145 | 10,265 | 43,937 | 108,809 | 219,685 | 544,045 | 1,701,937 | 8,509,685 | 90,202,661 | 451,013,305 |
| -1 | -5 | -53 | -265 | -829 | -2,053 | -4,145 | -10,265 | -43,937 | -108,809 | -219,685 | -544,045 | -1,701,937 | -8,509,685 | -90,202,661 | -451,013,305 |
