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 136,748,215, 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 | 136,748,215 | |
| -1 | -136,748,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,748,215.
Example:
1 x 136,748,215 = 136,748,215
and
-1 x -136,748,215 = 136,748,215
Notice both answers equal 136,748,215
With that explanation out of the way, let's continue. Next, we take the number 136,748,215 and divide it by 2:
136,748,215 ÷ 2 = 68,374,107.5
If the quotient is a whole number, then 2 and 68,374,107.5 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 | 136,748,215 | |
| -1 | -136,748,215 |
Now, we try dividing 136,748,215 by 3:
136,748,215 ÷ 3 = 45,582,738.3333
If the quotient is a whole number, then 3 and 45,582,738.3333 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 | 136,748,215 | |
| -1 | -136,748,215 |
Let's try dividing by 4:
136,748,215 ÷ 4 = 34,187,053.75
If the quotient is a whole number, then 4 and 34,187,053.75 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 | 136,748,215 | |
| -1 | 136,748,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 181 | 265 | 905 | 2,851 | 9,593 | 14,255 | 47,965 | 151,103 | 516,031 | 755,515 | 2,580,155 | 27,349,643 | 136,748,215 |
| -1 | -5 | -53 | -181 | -265 | -905 | -2,851 | -9,593 | -14,255 | -47,965 | -151,103 | -516,031 | -755,515 | -2,580,155 | -27,349,643 | -136,748,215 |
