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 530,261,413, 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 | 530,261,413 | |
| -1 | -530,261,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,261,413.
Example:
1 x 530,261,413 = 530,261,413
and
-1 x -530,261,413 = 530,261,413
Notice both answers equal 530,261,413
With that explanation out of the way, let's continue. Next, we take the number 530,261,413 and divide it by 2:
530,261,413 ÷ 2 = 265,130,706.5
If the quotient is a whole number, then 2 and 265,130,706.5 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 | 530,261,413 | |
| -1 | -530,261,413 |
Now, we try dividing 530,261,413 by 3:
530,261,413 ÷ 3 = 176,753,804.3333
If the quotient is a whole number, then 3 and 176,753,804.3333 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 | 530,261,413 | |
| -1 | -530,261,413 |
Let's try dividing by 4:
530,261,413 ÷ 4 = 132,565,353.25
If the quotient is a whole number, then 4 and 132,565,353.25 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 | 530,261,413 | |
| -1 | 530,261,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 239 | 1,111 | 1,997 | 2,629 | 21,967 | 24,139 | 201,697 | 265,529 | 477,283 | 2,218,667 | 5,250,113 | 48,205,583 | 530,261,413 |
| -1 | -11 | -101 | -239 | -1,111 | -1,997 | -2,629 | -21,967 | -24,139 | -201,697 | -265,529 | -477,283 | -2,218,667 | -5,250,113 | -48,205,583 | -530,261,413 |
