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 136,602,739, 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 | 136,602,739 | |
| -1 | -136,602,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,602,739.
Example:
1 x 136,602,739 = 136,602,739
and
-1 x -136,602,739 = 136,602,739
Notice both answers equal 136,602,739
With that explanation out of the way, let's continue. Next, we take the number 136,602,739 and divide it by 2:
136,602,739 ÷ 2 = 68,301,369.5
If the quotient is a whole number, then 2 and 68,301,369.5 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 | 136,602,739 | |
| -1 | -136,602,739 |
Now, we try dividing 136,602,739 by 3:
136,602,739 ÷ 3 = 45,534,246.3333
If the quotient is a whole number, then 3 and 45,534,246.3333 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 | 136,602,739 | |
| -1 | -136,602,739 |
Let's try dividing by 4:
136,602,739 ÷ 4 = 34,150,684.75
If the quotient is a whole number, then 4 and 34,150,684.75 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 | 136,602,739 | |
| -1 | 136,602,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 131 | 637 | 917 | 1,637 | 1,703 | 6,419 | 11,459 | 11,921 | 21,281 | 80,213 | 83,447 | 148,967 | 214,447 | 1,042,769 | 1,501,129 | 2,787,811 | 10,507,903 | 19,514,677 | 136,602,739 |
| -1 | -7 | -13 | -49 | -91 | -131 | -637 | -917 | -1,637 | -1,703 | -6,419 | -11,459 | -11,921 | -21,281 | -80,213 | -83,447 | -148,967 | -214,447 | -1,042,769 | -1,501,129 | -2,787,811 | -10,507,903 | -19,514,677 | -136,602,739 |
