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 135,460,715, 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 | 135,460,715 | |
| -1 | -135,460,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,460,715.
Example:
1 x 135,460,715 = 135,460,715
and
-1 x -135,460,715 = 135,460,715
Notice both answers equal 135,460,715
With that explanation out of the way, let's continue. Next, we take the number 135,460,715 and divide it by 2:
135,460,715 ÷ 2 = 67,730,357.5
If the quotient is a whole number, then 2 and 67,730,357.5 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 | 135,460,715 | |
| -1 | -135,460,715 |
Now, we try dividing 135,460,715 by 3:
135,460,715 ÷ 3 = 45,153,571.6667
If the quotient is a whole number, then 3 and 45,153,571.6667 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 | 135,460,715 | |
| -1 | -135,460,715 |
Let's try dividing by 4:
135,460,715 ÷ 4 = 33,865,178.75
If the quotient is a whole number, then 4 and 33,865,178.75 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 | 135,460,715 | |
| -1 | 135,460,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 311 | 1,555 | 4,043 | 6,701 | 20,215 | 33,505 | 87,113 | 435,565 | 2,084,011 | 10,420,055 | 27,092,143 | 135,460,715 |
| -1 | -5 | -13 | -65 | -311 | -1,555 | -4,043 | -6,701 | -20,215 | -33,505 | -87,113 | -435,565 | -2,084,011 | -10,420,055 | -27,092,143 | -135,460,715 |
