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 136,441,261, 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 | 136,441,261 | |
| -1 | -136,441,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,441,261.
Example:
1 x 136,441,261 = 136,441,261
and
-1 x -136,441,261 = 136,441,261
Notice both answers equal 136,441,261
With that explanation out of the way, let's continue. Next, we take the number 136,441,261 and divide it by 2:
136,441,261 ÷ 2 = 68,220,630.5
If the quotient is a whole number, then 2 and 68,220,630.5 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 | 136,441,261 | |
| -1 | -136,441,261 |
Now, we try dividing 136,441,261 by 3:
136,441,261 ÷ 3 = 45,480,420.3333
If the quotient is a whole number, then 3 and 45,480,420.3333 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 | 136,441,261 | |
| -1 | -136,441,261 |
Let's try dividing by 4:
136,441,261 ÷ 4 = 34,110,315.25
If the quotient is a whole number, then 4 and 34,110,315.25 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 | 136,441,261 | |
| -1 | 136,441,261 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 31 | 209 | 341 | 589 | 6,479 | 21,059 | 231,649 | 400,121 | 652,829 | 4,401,331 | 7,181,119 | 12,403,751 | 136,441,261 |
| -1 | -11 | -19 | -31 | -209 | -341 | -589 | -6,479 | -21,059 | -231,649 | -400,121 | -652,829 | -4,401,331 | -7,181,119 | -12,403,751 | -136,441,261 |
