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 520,530,541, 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 | 520,530,541 | |
| -1 | -520,530,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,530,541.
Example:
1 x 520,530,541 = 520,530,541
and
-1 x -520,530,541 = 520,530,541
Notice both answers equal 520,530,541
With that explanation out of the way, let's continue. Next, we take the number 520,530,541 and divide it by 2:
520,530,541 ÷ 2 = 260,265,270.5
If the quotient is a whole number, then 2 and 260,265,270.5 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 | 520,530,541 | |
| -1 | -520,530,541 |
Now, we try dividing 520,530,541 by 3:
520,530,541 ÷ 3 = 173,510,180.3333
If the quotient is a whole number, then 3 and 173,510,180.3333 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 | 520,530,541 | |
| -1 | -520,530,541 |
Let's try dividing by 4:
520,530,541 ÷ 4 = 130,132,635.25
If the quotient is a whole number, then 4 and 130,132,635.25 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 | 520,530,541 | |
| -1 | 520,530,541 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 137 | 1,073 | 3,541 | 3,973 | 5,069 | 102,689 | 131,017 | 147,001 | 485,117 | 3,799,493 | 14,068,393 | 17,949,329 | 520,530,541 |
| -1 | -29 | -37 | -137 | -1,073 | -3,541 | -3,973 | -5,069 | -102,689 | -131,017 | -147,001 | -485,117 | -3,799,493 | -14,068,393 | -17,949,329 | -520,530,541 |
