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 51,569,609, 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 | 51,569,609 | |
| -1 | -51,569,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,569,609.
Example:
1 x 51,569,609 = 51,569,609
and
-1 x -51,569,609 = 51,569,609
Notice both answers equal 51,569,609
With that explanation out of the way, let's continue. Next, we take the number 51,569,609 and divide it by 2:
51,569,609 ÷ 2 = 25,784,804.5
If the quotient is a whole number, then 2 and 25,784,804.5 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 | 51,569,609 | |
| -1 | -51,569,609 |
Now, we try dividing 51,569,609 by 3:
51,569,609 ÷ 3 = 17,189,869.6667
If the quotient is a whole number, then 3 and 17,189,869.6667 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 | 51,569,609 | |
| -1 | -51,569,609 |
Let's try dividing by 4:
51,569,609 ÷ 4 = 12,892,402.25
If the quotient is a whole number, then 4 and 12,892,402.25 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 | 51,569,609 | |
| -1 | 51,569,609 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 73 | 91 | 511 | 637 | 949 | 1,109 | 3,577 | 6,643 | 7,763 | 14,417 | 46,501 | 54,341 | 80,957 | 100,919 | 566,699 | 706,433 | 1,052,441 | 3,966,893 | 7,367,087 | 51,569,609 |
| -1 | -7 | -13 | -49 | -73 | -91 | -511 | -637 | -949 | -1,109 | -3,577 | -6,643 | -7,763 | -14,417 | -46,501 | -54,341 | -80,957 | -100,919 | -566,699 | -706,433 | -1,052,441 | -3,966,893 | -7,367,087 | -51,569,609 |
