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 56,006,509, 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 | 56,006,509 | |
| -1 | -56,006,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,006,509.
Example:
1 x 56,006,509 = 56,006,509
and
-1 x -56,006,509 = 56,006,509
Notice both answers equal 56,006,509
With that explanation out of the way, let's continue. Next, we take the number 56,006,509 and divide it by 2:
56,006,509 ÷ 2 = 28,003,254.5
If the quotient is a whole number, then 2 and 28,003,254.5 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 | 56,006,509 | |
| -1 | -56,006,509 |
Now, we try dividing 56,006,509 by 3:
56,006,509 ÷ 3 = 18,668,836.3333
If the quotient is a whole number, then 3 and 18,668,836.3333 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 | 56,006,509 | |
| -1 | -56,006,509 |
Let's try dividing by 4:
56,006,509 ÷ 4 = 14,001,627.25
If the quotient is a whole number, then 4 and 14,001,627.25 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 | 56,006,509 | |
| -1 | 56,006,509 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 197 | 247 | 1,151 | 2,561 | 3,743 | 14,963 | 21,869 | 48,659 | 226,747 | 284,297 | 2,947,711 | 4,308,193 | 56,006,509 |
| -1 | -13 | -19 | -197 | -247 | -1,151 | -2,561 | -3,743 | -14,963 | -21,869 | -48,659 | -226,747 | -284,297 | -2,947,711 | -4,308,193 | -56,006,509 |
