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 136,011,253, 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 | 136,011,253 | |
| -1 | -136,011,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,011,253.
Example:
1 x 136,011,253 = 136,011,253
and
-1 x -136,011,253 = 136,011,253
Notice both answers equal 136,011,253
With that explanation out of the way, let's continue. Next, we take the number 136,011,253 and divide it by 2:
136,011,253 ÷ 2 = 68,005,626.5
If the quotient is a whole number, then 2 and 68,005,626.5 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 | 136,011,253 | |
| -1 | -136,011,253 |
Now, we try dividing 136,011,253 by 3:
136,011,253 ÷ 3 = 45,337,084.3333
If the quotient is a whole number, then 3 and 45,337,084.3333 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 | 136,011,253 | |
| -1 | -136,011,253 |
Let's try dividing by 4:
136,011,253 ÷ 4 = 34,002,813.25
If the quotient is a whole number, then 4 and 34,002,813.25 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 | 136,011,253 | |
| -1 | 136,011,253 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 353 | 2,471 | 2,897 | 6,707 | 20,279 | 46,949 | 55,043 | 385,301 | 1,022,641 | 7,158,487 | 19,430,179 | 136,011,253 |
| -1 | -7 | -19 | -133 | -353 | -2,471 | -2,897 | -6,707 | -20,279 | -46,949 | -55,043 | -385,301 | -1,022,641 | -7,158,487 | -19,430,179 | -136,011,253 |
