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 52,156,205, 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 | 52,156,205 | |
| -1 | -52,156,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,156,205.
Example:
1 x 52,156,205 = 52,156,205
and
-1 x -52,156,205 = 52,156,205
Notice both answers equal 52,156,205
With that explanation out of the way, let's continue. Next, we take the number 52,156,205 and divide it by 2:
52,156,205 ÷ 2 = 26,078,102.5
If the quotient is a whole number, then 2 and 26,078,102.5 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 | 52,156,205 | |
| -1 | -52,156,205 |
Now, we try dividing 52,156,205 by 3:
52,156,205 ÷ 3 = 17,385,401.6667
If the quotient is a whole number, then 3 and 17,385,401.6667 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 | 52,156,205 | |
| -1 | -52,156,205 |
Let's try dividing by 4:
52,156,205 ÷ 4 = 13,039,051.25
If the quotient is a whole number, then 4 and 13,039,051.25 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 | 52,156,205 | |
| -1 | 52,156,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 367 | 661 | 1,835 | 3,305 | 15,781 | 28,423 | 78,905 | 142,115 | 242,587 | 1,212,935 | 10,431,241 | 52,156,205 |
| -1 | -5 | -43 | -215 | -367 | -661 | -1,835 | -3,305 | -15,781 | -28,423 | -78,905 | -142,115 | -242,587 | -1,212,935 | -10,431,241 | -52,156,205 |
