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 52,689,413, 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 | 52,689,413 | |
| -1 | -52,689,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,689,413.
Example:
1 x 52,689,413 = 52,689,413
and
-1 x -52,689,413 = 52,689,413
Notice both answers equal 52,689,413
With that explanation out of the way, let's continue. Next, we take the number 52,689,413 and divide it by 2:
52,689,413 ÷ 2 = 26,344,706.5
If the quotient is a whole number, then 2 and 26,344,706.5 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 | 52,689,413 | |
| -1 | -52,689,413 |
Now, we try dividing 52,689,413 by 3:
52,689,413 ÷ 3 = 17,563,137.6667
If the quotient is a whole number, then 3 and 17,563,137.6667 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 | 52,689,413 | |
| -1 | -52,689,413 |
Let's try dividing by 4:
52,689,413 ÷ 4 = 13,172,353.25
If the quotient is a whole number, then 4 and 13,172,353.25 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 | 52,689,413 | |
| -1 | 52,689,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 421 | 941 | 2,947 | 6,587 | 7,999 | 17,879 | 55,993 | 125,153 | 396,161 | 2,773,127 | 7,527,059 | 52,689,413 |
| -1 | -7 | -19 | -133 | -421 | -941 | -2,947 | -6,587 | -7,999 | -17,879 | -55,993 | -125,153 | -396,161 | -2,773,127 | -7,527,059 | -52,689,413 |
