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 135,430,015, 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 | 135,430,015 | |
| -1 | -135,430,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,430,015.
Example:
1 x 135,430,015 = 135,430,015
and
-1 x -135,430,015 = 135,430,015
Notice both answers equal 135,430,015
With that explanation out of the way, let's continue. Next, we take the number 135,430,015 and divide it by 2:
135,430,015 ÷ 2 = 67,715,007.5
If the quotient is a whole number, then 2 and 67,715,007.5 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 | 135,430,015 | |
| -1 | -135,430,015 |
Now, we try dividing 135,430,015 by 3:
135,430,015 ÷ 3 = 45,143,338.3333
If the quotient is a whole number, then 3 and 45,143,338.3333 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 | 135,430,015 | |
| -1 | -135,430,015 |
Let's try dividing by 4:
135,430,015 ÷ 4 = 33,857,503.75
If the quotient is a whole number, then 4 and 33,857,503.75 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 | 135,430,015 | |
| -1 | 135,430,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 54,499 | 272,495 | 381,493 | 1,907,465 | 3,869,429 | 19,347,145 | 27,086,003 | 135,430,015 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -54,499 | -272,495 | -381,493 | -1,907,465 | -3,869,429 | -19,347,145 | -27,086,003 | -135,430,015 |
