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 71,404,135, 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 | 71,404,135 | |
| -1 | -71,404,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,404,135.
Example:
1 x 71,404,135 = 71,404,135
and
-1 x -71,404,135 = 71,404,135
Notice both answers equal 71,404,135
With that explanation out of the way, let's continue. Next, we take the number 71,404,135 and divide it by 2:
71,404,135 ÷ 2 = 35,702,067.5
If the quotient is a whole number, then 2 and 35,702,067.5 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 | 71,404,135 | |
| -1 | -71,404,135 |
Now, we try dividing 71,404,135 by 3:
71,404,135 ÷ 3 = 23,801,378.3333
If the quotient is a whole number, then 3 and 23,801,378.3333 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 | 71,404,135 | |
| -1 | -71,404,135 |
Let's try dividing by 4:
71,404,135 ÷ 4 = 17,851,033.75
If the quotient is a whole number, then 4 and 17,851,033.75 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 | 71,404,135 | |
| -1 | 71,404,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 113 | 565 | 1,243 | 6,215 | 11,489 | 57,445 | 126,379 | 631,895 | 1,298,257 | 6,491,285 | 14,280,827 | 71,404,135 |
| -1 | -5 | -11 | -55 | -113 | -565 | -1,243 | -6,215 | -11,489 | -57,445 | -126,379 | -631,895 | -1,298,257 | -6,491,285 | -14,280,827 | -71,404,135 |
