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 51,343,019, 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 | 51,343,019 | |
| -1 | -51,343,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,343,019.
Example:
1 x 51,343,019 = 51,343,019
and
-1 x -51,343,019 = 51,343,019
Notice both answers equal 51,343,019
With that explanation out of the way, let's continue. Next, we take the number 51,343,019 and divide it by 2:
51,343,019 ÷ 2 = 25,671,509.5
If the quotient is a whole number, then 2 and 25,671,509.5 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 | 51,343,019 | |
| -1 | -51,343,019 |
Now, we try dividing 51,343,019 by 3:
51,343,019 ÷ 3 = 17,114,339.6667
If the quotient is a whole number, then 3 and 17,114,339.6667 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 | 51,343,019 | |
| -1 | -51,343,019 |
Let's try dividing by 4:
51,343,019 ÷ 4 = 12,835,754.75
If the quotient is a whole number, then 4 and 12,835,754.75 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 | 51,343,019 | |
| -1 | 51,343,019 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 113 | 791 | 1,469 | 4,993 | 10,283 | 34,951 | 64,909 | 454,363 | 564,209 | 3,949,463 | 7,334,717 | 51,343,019 |
| -1 | -7 | -13 | -91 | -113 | -791 | -1,469 | -4,993 | -10,283 | -34,951 | -64,909 | -454,363 | -564,209 | -3,949,463 | -7,334,717 | -51,343,019 |
