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 136,531,535, 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 | 136,531,535 | |
| -1 | -136,531,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,531,535.
Example:
1 x 136,531,535 = 136,531,535
and
-1 x -136,531,535 = 136,531,535
Notice both answers equal 136,531,535
With that explanation out of the way, let's continue. Next, we take the number 136,531,535 and divide it by 2:
136,531,535 ÷ 2 = 68,265,767.5
If the quotient is a whole number, then 2 and 68,265,767.5 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 | 136,531,535 | |
| -1 | -136,531,535 |
Now, we try dividing 136,531,535 by 3:
136,531,535 ÷ 3 = 45,510,511.6667
If the quotient is a whole number, then 3 and 45,510,511.6667 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 | 136,531,535 | |
| -1 | -136,531,535 |
Let's try dividing by 4:
136,531,535 ÷ 4 = 34,132,883.75
If the quotient is a whole number, then 4 and 34,132,883.75 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 | 136,531,535 | |
| -1 | 136,531,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 53,437 | 267,185 | 374,059 | 1,870,295 | 3,900,901 | 19,504,505 | 27,306,307 | 136,531,535 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -53,437 | -267,185 | -374,059 | -1,870,295 | -3,900,901 | -19,504,505 | -27,306,307 | -136,531,535 |
