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 470,783,525, 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 | 470,783,525 | |
| -1 | -470,783,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 470,783,525.
Example:
1 x 470,783,525 = 470,783,525
and
-1 x -470,783,525 = 470,783,525
Notice both answers equal 470,783,525
With that explanation out of the way, let's continue. Next, we take the number 470,783,525 and divide it by 2:
470,783,525 ÷ 2 = 235,391,762.5
If the quotient is a whole number, then 2 and 235,391,762.5 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 | 470,783,525 | |
| -1 | -470,783,525 |
Now, we try dividing 470,783,525 by 3:
470,783,525 ÷ 3 = 156,927,841.6667
If the quotient is a whole number, then 3 and 156,927,841.6667 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 | 470,783,525 | |
| -1 | -470,783,525 |
Let's try dividing by 4:
470,783,525 ÷ 4 = 117,695,881.25
If the quotient is a whole number, then 4 and 117,695,881.25 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 | 470,783,525 | |
| -1 | 470,783,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 205 | 1,025 | 459,301 | 2,296,505 | 11,482,525 | 18,831,341 | 94,156,705 | 470,783,525 |
| -1 | -5 | -25 | -41 | -205 | -1,025 | -459,301 | -2,296,505 | -11,482,525 | -18,831,341 | -94,156,705 | -470,783,525 |
