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 512,460,085, 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 | 512,460,085 | |
| -1 | -512,460,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 512,460,085.
Example:
1 x 512,460,085 = 512,460,085
and
-1 x -512,460,085 = 512,460,085
Notice both answers equal 512,460,085
With that explanation out of the way, let's continue. Next, we take the number 512,460,085 and divide it by 2:
512,460,085 ÷ 2 = 256,230,042.5
If the quotient is a whole number, then 2 and 256,230,042.5 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 | 512,460,085 | |
| -1 | -512,460,085 |
Now, we try dividing 512,460,085 by 3:
512,460,085 ÷ 3 = 170,820,028.3333
If the quotient is a whole number, then 3 and 170,820,028.3333 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 | 512,460,085 | |
| -1 | -512,460,085 |
Let's try dividing by 4:
512,460,085 ÷ 4 = 128,115,021.25
If the quotient is a whole number, then 4 and 128,115,021.25 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 | 512,460,085 | |
| -1 | 512,460,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 113 | 305 | 565 | 6,893 | 14,869 | 34,465 | 74,345 | 907,009 | 1,680,197 | 4,535,045 | 8,400,985 | 102,492,017 | 512,460,085 |
| -1 | -5 | -61 | -113 | -305 | -565 | -6,893 | -14,869 | -34,465 | -74,345 | -907,009 | -1,680,197 | -4,535,045 | -8,400,985 | -102,492,017 | -512,460,085 |
