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 262,426,205, 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 | 262,426,205 | |
| -1 | -262,426,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,426,205.
Example:
1 x 262,426,205 = 262,426,205
and
-1 x -262,426,205 = 262,426,205
Notice both answers equal 262,426,205
With that explanation out of the way, let's continue. Next, we take the number 262,426,205 and divide it by 2:
262,426,205 ÷ 2 = 131,213,102.5
If the quotient is a whole number, then 2 and 131,213,102.5 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 | 262,426,205 | |
| -1 | -262,426,205 |
Now, we try dividing 262,426,205 by 3:
262,426,205 ÷ 3 = 87,475,401.6667
If the quotient is a whole number, then 3 and 87,475,401.6667 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 | 262,426,205 | |
| -1 | -262,426,205 |
Let's try dividing by 4:
262,426,205 ÷ 4 = 65,606,551.25
If the quotient is a whole number, then 4 and 65,606,551.25 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 | 262,426,205 | |
| -1 | 262,426,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 4,945 | 53,069 | 265,345 | 1,220,587 | 2,281,967 | 6,102,935 | 11,409,835 | 52,485,241 | 262,426,205 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -4,945 | -53,069 | -265,345 | -1,220,587 | -2,281,967 | -6,102,935 | -11,409,835 | -52,485,241 | -262,426,205 |
