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 265,166,281, 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 | 265,166,281 | |
| -1 | -265,166,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,166,281.
Example:
1 x 265,166,281 = 265,166,281
and
-1 x -265,166,281 = 265,166,281
Notice both answers equal 265,166,281
With that explanation out of the way, let's continue. Next, we take the number 265,166,281 and divide it by 2:
265,166,281 ÷ 2 = 132,583,140.5
If the quotient is a whole number, then 2 and 132,583,140.5 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 | 265,166,281 | |
| -1 | -265,166,281 |
Now, we try dividing 265,166,281 by 3:
265,166,281 ÷ 3 = 88,388,760.3333
If the quotient is a whole number, then 3 and 88,388,760.3333 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 | 265,166,281 | |
| -1 | -265,166,281 |
Let's try dividing by 4:
265,166,281 ÷ 4 = 66,291,570.25
If the quotient is a whole number, then 4 and 66,291,570.25 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 | 265,166,281 | |
| -1 | 265,166,281 |
If you did it right, you will end up with this table:
| 1 | 31 | 97 | 163 | 541 | 3,007 | 5,053 | 15,811 | 16,771 | 52,477 | 88,183 | 490,141 | 1,626,787 | 2,733,673 | 8,553,751 | 265,166,281 |
| -1 | -31 | -97 | -163 | -541 | -3,007 | -5,053 | -15,811 | -16,771 | -52,477 | -88,183 | -490,141 | -1,626,787 | -2,733,673 | -8,553,751 | -265,166,281 |
