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 464,724,685, 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 | 464,724,685 | |
| -1 | -464,724,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 464,724,685.
Example:
1 x 464,724,685 = 464,724,685
and
-1 x -464,724,685 = 464,724,685
Notice both answers equal 464,724,685
With that explanation out of the way, let's continue. Next, we take the number 464,724,685 and divide it by 2:
464,724,685 ÷ 2 = 232,362,342.5
If the quotient is a whole number, then 2 and 232,362,342.5 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 | 464,724,685 | |
| -1 | -464,724,685 |
Now, we try dividing 464,724,685 by 3:
464,724,685 ÷ 3 = 154,908,228.3333
If the quotient is a whole number, then 3 and 154,908,228.3333 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 | 464,724,685 | |
| -1 | -464,724,685 |
Let's try dividing by 4:
464,724,685 ÷ 4 = 116,181,171.25
If the quotient is a whole number, then 4 and 116,181,171.25 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 | 464,724,685 | |
| -1 | 464,724,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 337 | 389 | 709 | 1,685 | 1,945 | 3,545 | 131,093 | 238,933 | 275,801 | 655,465 | 1,194,665 | 1,379,005 | 92,944,937 | 464,724,685 |
| -1 | -5 | -337 | -389 | -709 | -1,685 | -1,945 | -3,545 | -131,093 | -238,933 | -275,801 | -655,465 | -1,194,665 | -1,379,005 | -92,944,937 | -464,724,685 |
