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 516,564,169, 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 | 516,564,169 | |
| -1 | -516,564,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 516,564,169.
Example:
1 x 516,564,169 = 516,564,169
and
-1 x -516,564,169 = 516,564,169
Notice both answers equal 516,564,169
With that explanation out of the way, let's continue. Next, we take the number 516,564,169 and divide it by 2:
516,564,169 ÷ 2 = 258,282,084.5
If the quotient is a whole number, then 2 and 258,282,084.5 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 | 516,564,169 | |
| -1 | -516,564,169 |
Now, we try dividing 516,564,169 by 3:
516,564,169 ÷ 3 = 172,188,056.3333
If the quotient is a whole number, then 3 and 172,188,056.3333 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 | 516,564,169 | |
| -1 | -516,564,169 |
Let's try dividing by 4:
516,564,169 ÷ 4 = 129,141,042.25
If the quotient is a whole number, then 4 and 129,141,042.25 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 | 516,564,169 | |
| -1 | 516,564,169 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 517 | 821 | 1,217 | 9,031 | 13,387 | 38,587 | 57,199 | 424,457 | 629,189 | 999,157 | 10,990,727 | 46,960,379 | 516,564,169 |
| -1 | -11 | -47 | -517 | -821 | -1,217 | -9,031 | -13,387 | -38,587 | -57,199 | -424,457 | -629,189 | -999,157 | -10,990,727 | -46,960,379 | -516,564,169 |
