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 51,624,205, 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 | 51,624,205 | |
| -1 | -51,624,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,624,205.
Example:
1 x 51,624,205 = 51,624,205
and
-1 x -51,624,205 = 51,624,205
Notice both answers equal 51,624,205
With that explanation out of the way, let's continue. Next, we take the number 51,624,205 and divide it by 2:
51,624,205 ÷ 2 = 25,812,102.5
If the quotient is a whole number, then 2 and 25,812,102.5 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 | 51,624,205 | |
| -1 | -51,624,205 |
Now, we try dividing 51,624,205 by 3:
51,624,205 ÷ 3 = 17,208,068.3333
If the quotient is a whole number, then 3 and 17,208,068.3333 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 | 51,624,205 | |
| -1 | -51,624,205 |
Let's try dividing by 4:
51,624,205 ÷ 4 = 12,906,051.25
If the quotient is a whole number, then 4 and 12,906,051.25 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 | 51,624,205 | |
| -1 | 51,624,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 439 | 811 | 2,195 | 4,055 | 12,731 | 23,519 | 63,655 | 117,595 | 356,029 | 1,780,145 | 10,324,841 | 51,624,205 |
| -1 | -5 | -29 | -145 | -439 | -811 | -2,195 | -4,055 | -12,731 | -23,519 | -63,655 | -117,595 | -356,029 | -1,780,145 | -10,324,841 | -51,624,205 |
