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 136,066,553, 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 | 136,066,553 | |
| -1 | -136,066,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,066,553.
Example:
1 x 136,066,553 = 136,066,553
and
-1 x -136,066,553 = 136,066,553
Notice both answers equal 136,066,553
With that explanation out of the way, let's continue. Next, we take the number 136,066,553 and divide it by 2:
136,066,553 ÷ 2 = 68,033,276.5
If the quotient is a whole number, then 2 and 68,033,276.5 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 | 136,066,553 | |
| -1 | -136,066,553 |
Now, we try dividing 136,066,553 by 3:
136,066,553 ÷ 3 = 45,355,517.6667
If the quotient is a whole number, then 3 and 45,355,517.6667 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 | 136,066,553 | |
| -1 | -136,066,553 |
Let's try dividing by 4:
136,066,553 ÷ 4 = 34,016,638.25
If the quotient is a whole number, then 4 and 34,016,638.25 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 | 136,066,553 | |
| -1 | 136,066,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 151 | 763 | 1,057 | 1,181 | 8,267 | 16,459 | 115,213 | 128,729 | 178,331 | 901,103 | 1,248,317 | 19,438,079 | 136,066,553 |
| -1 | -7 | -109 | -151 | -763 | -1,057 | -1,181 | -8,267 | -16,459 | -115,213 | -128,729 | -178,331 | -901,103 | -1,248,317 | -19,438,079 | -136,066,553 |
