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 55,266,565, 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 | 55,266,565 | |
| -1 | -55,266,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,266,565.
Example:
1 x 55,266,565 = 55,266,565
and
-1 x -55,266,565 = 55,266,565
Notice both answers equal 55,266,565
With that explanation out of the way, let's continue. Next, we take the number 55,266,565 and divide it by 2:
55,266,565 ÷ 2 = 27,633,282.5
If the quotient is a whole number, then 2 and 27,633,282.5 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 | 55,266,565 | |
| -1 | -55,266,565 |
Now, we try dividing 55,266,565 by 3:
55,266,565 ÷ 3 = 18,422,188.3333
If the quotient is a whole number, then 3 and 18,422,188.3333 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 | 55,266,565 | |
| -1 | -55,266,565 |
Let's try dividing by 4:
55,266,565 ÷ 4 = 13,816,641.25
If the quotient is a whole number, then 4 and 13,816,641.25 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 | 55,266,565 | |
| -1 | 55,266,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 257 | 1,049 | 1,285 | 5,245 | 10,537 | 43,009 | 52,685 | 215,045 | 269,593 | 1,347,965 | 11,053,313 | 55,266,565 |
| -1 | -5 | -41 | -205 | -257 | -1,049 | -1,285 | -5,245 | -10,537 | -43,009 | -52,685 | -215,045 | -269,593 | -1,347,965 | -11,053,313 | -55,266,565 |
