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 51,601,043, 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 | 51,601,043 | |
| -1 | -51,601,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,601,043.
Example:
1 x 51,601,043 = 51,601,043
and
-1 x -51,601,043 = 51,601,043
Notice both answers equal 51,601,043
With that explanation out of the way, let's continue. Next, we take the number 51,601,043 and divide it by 2:
51,601,043 ÷ 2 = 25,800,521.5
If the quotient is a whole number, then 2 and 25,800,521.5 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 | 51,601,043 | |
| -1 | -51,601,043 |
Now, we try dividing 51,601,043 by 3:
51,601,043 ÷ 3 = 17,200,347.6667
If the quotient is a whole number, then 3 and 17,200,347.6667 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 | 51,601,043 | |
| -1 | -51,601,043 |
Let's try dividing by 4:
51,601,043 ÷ 4 = 12,900,260.75
If the quotient is a whole number, then 4 and 12,900,260.75 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 | 51,601,043 | |
| -1 | 51,601,043 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 103 | 433 | 1,157 | 1,339 | 5,629 | 9,167 | 38,537 | 44,599 | 119,171 | 500,981 | 579,787 | 3,969,311 | 51,601,043 |
| -1 | -13 | -89 | -103 | -433 | -1,157 | -1,339 | -5,629 | -9,167 | -38,537 | -44,599 | -119,171 | -500,981 | -579,787 | -3,969,311 | -51,601,043 |
