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 464,044,505, 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 | 464,044,505 | |
| -1 | -464,044,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 464,044,505.
Example:
1 x 464,044,505 = 464,044,505
and
-1 x -464,044,505 = 464,044,505
Notice both answers equal 464,044,505
With that explanation out of the way, let's continue. Next, we take the number 464,044,505 and divide it by 2:
464,044,505 ÷ 2 = 232,022,252.5
If the quotient is a whole number, then 2 and 232,022,252.5 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 | 464,044,505 | |
| -1 | -464,044,505 |
Now, we try dividing 464,044,505 by 3:
464,044,505 ÷ 3 = 154,681,501.6667
If the quotient is a whole number, then 3 and 154,681,501.6667 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 | 464,044,505 | |
| -1 | -464,044,505 |
Let's try dividing by 4:
464,044,505 ÷ 4 = 116,011,126.25
If the quotient is a whole number, then 4 and 116,011,126.25 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 | 464,044,505 | |
| -1 | 464,044,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 691 | 3,455 | 7,069 | 13,129 | 35,345 | 65,645 | 134,311 | 671,555 | 4,884,679 | 24,423,395 | 92,808,901 | 464,044,505 |
| -1 | -5 | -19 | -95 | -691 | -3,455 | -7,069 | -13,129 | -35,345 | -65,645 | -134,311 | -671,555 | -4,884,679 | -24,423,395 | -92,808,901 | -464,044,505 |
