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 382,746,545, 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 | 382,746,545 | |
| -1 | -382,746,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 382,746,545.
Example:
1 x 382,746,545 = 382,746,545
and
-1 x -382,746,545 = 382,746,545
Notice both answers equal 382,746,545
With that explanation out of the way, let's continue. Next, we take the number 382,746,545 and divide it by 2:
382,746,545 ÷ 2 = 191,373,272.5
If the quotient is a whole number, then 2 and 191,373,272.5 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 | 382,746,545 | |
| -1 | -382,746,545 |
Now, we try dividing 382,746,545 by 3:
382,746,545 ÷ 3 = 127,582,181.6667
If the quotient is a whole number, then 3 and 127,582,181.6667 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 | 382,746,545 | |
| -1 | -382,746,545 |
Let's try dividing by 4:
382,746,545 ÷ 4 = 95,686,636.25
If the quotient is a whole number, then 4 and 95,686,636.25 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 | 382,746,545 | |
| -1 | 382,746,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 67 | 95 | 335 | 1,273 | 6,365 | 60,133 | 300,665 | 1,142,527 | 4,028,911 | 5,712,635 | 20,144,555 | 76,549,309 | 382,746,545 |
| -1 | -5 | -19 | -67 | -95 | -335 | -1,273 | -6,365 | -60,133 | -300,665 | -1,142,527 | -4,028,911 | -5,712,635 | -20,144,555 | -76,549,309 | -382,746,545 |
