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 136,011,145, 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 | 136,011,145 | |
| -1 | -136,011,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,011,145.
Example:
1 x 136,011,145 = 136,011,145
and
-1 x -136,011,145 = 136,011,145
Notice both answers equal 136,011,145
With that explanation out of the way, let's continue. Next, we take the number 136,011,145 and divide it by 2:
136,011,145 ÷ 2 = 68,005,572.5
If the quotient is a whole number, then 2 and 68,005,572.5 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 | 136,011,145 | |
| -1 | -136,011,145 |
Now, we try dividing 136,011,145 by 3:
136,011,145 ÷ 3 = 45,337,048.3333
If the quotient is a whole number, then 3 and 45,337,048.3333 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 | 136,011,145 | |
| -1 | -136,011,145 |
Let's try dividing by 4:
136,011,145 ÷ 4 = 34,002,786.25
If the quotient is a whole number, then 4 and 34,002,786.25 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 | 136,011,145 | |
| -1 | 136,011,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 101 | 205 | 505 | 4,141 | 6,569 | 20,705 | 32,845 | 269,329 | 663,469 | 1,346,645 | 3,317,345 | 27,202,229 | 136,011,145 |
| -1 | -5 | -41 | -101 | -205 | -505 | -4,141 | -6,569 | -20,705 | -32,845 | -269,329 | -663,469 | -1,346,645 | -3,317,345 | -27,202,229 | -136,011,145 |
