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 411,315,625, 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 | 411,315,625 | |
| -1 | -411,315,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,315,625.
Example:
1 x 411,315,625 = 411,315,625
and
-1 x -411,315,625 = 411,315,625
Notice both answers equal 411,315,625
With that explanation out of the way, let's continue. Next, we take the number 411,315,625 and divide it by 2:
411,315,625 ÷ 2 = 205,657,812.5
If the quotient is a whole number, then 2 and 205,657,812.5 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 | 411,315,625 | |
| -1 | -411,315,625 |
Now, we try dividing 411,315,625 by 3:
411,315,625 ÷ 3 = 137,105,208.3333
If the quotient is a whole number, then 3 and 137,105,208.3333 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 | 411,315,625 | |
| -1 | -411,315,625 |
Let's try dividing by 4:
411,315,625 ÷ 4 = 102,828,906.25
If the quotient is a whole number, then 4 and 102,828,906.25 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 | 411,315,625 | |
| -1 | 411,315,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 625 | 875 | 3,125 | 4,375 | 18,803 | 21,875 | 94,015 | 131,621 | 470,075 | 658,105 | 2,350,375 | 3,290,525 | 11,751,875 | 16,452,625 | 58,759,375 | 82,263,125 | 411,315,625 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -625 | -875 | -3,125 | -4,375 | -18,803 | -21,875 | -94,015 | -131,621 | -470,075 | -658,105 | -2,350,375 | -3,290,525 | -11,751,875 | -16,452,625 | -58,759,375 | -82,263,125 | -411,315,625 |
