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 134,535,415, 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 | 134,535,415 | |
| -1 | -134,535,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,535,415.
Example:
1 x 134,535,415 = 134,535,415
and
-1 x -134,535,415 = 134,535,415
Notice both answers equal 134,535,415
With that explanation out of the way, let's continue. Next, we take the number 134,535,415 and divide it by 2:
134,535,415 ÷ 2 = 67,267,707.5
If the quotient is a whole number, then 2 and 67,267,707.5 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 | 134,535,415 | |
| -1 | -134,535,415 |
Now, we try dividing 134,535,415 by 3:
134,535,415 ÷ 3 = 44,845,138.3333
If the quotient is a whole number, then 3 and 44,845,138.3333 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 | 134,535,415 | |
| -1 | -134,535,415 |
Let's try dividing by 4:
134,535,415 ÷ 4 = 33,633,853.75
If the quotient is a whole number, then 4 and 33,633,853.75 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 | 134,535,415 | |
| -1 | 134,535,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 54,139 | 270,695 | 378,973 | 1,894,865 | 3,843,869 | 19,219,345 | 26,907,083 | 134,535,415 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -54,139 | -270,695 | -378,973 | -1,894,865 | -3,843,869 | -19,219,345 | -26,907,083 | -134,535,415 |
