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 71,140,795, 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 | 71,140,795 | |
| -1 | -71,140,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,140,795.
Example:
1 x 71,140,795 = 71,140,795
and
-1 x -71,140,795 = 71,140,795
Notice both answers equal 71,140,795
With that explanation out of the way, let's continue. Next, we take the number 71,140,795 and divide it by 2:
71,140,795 ÷ 2 = 35,570,397.5
If the quotient is a whole number, then 2 and 35,570,397.5 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 | 71,140,795 | |
| -1 | -71,140,795 |
Now, we try dividing 71,140,795 by 3:
71,140,795 ÷ 3 = 23,713,598.3333
If the quotient is a whole number, then 3 and 23,713,598.3333 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 | 71,140,795 | |
| -1 | -71,140,795 |
Let's try dividing by 4:
71,140,795 ÷ 4 = 17,785,198.75
If the quotient is a whole number, then 4 and 17,785,198.75 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 | 71,140,795 | |
| -1 | 71,140,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 149 | 745 | 1,639 | 8,195 | 8,681 | 43,405 | 95,491 | 477,455 | 1,293,469 | 6,467,345 | 14,228,159 | 71,140,795 |
| -1 | -5 | -11 | -55 | -149 | -745 | -1,639 | -8,195 | -8,681 | -43,405 | -95,491 | -477,455 | -1,293,469 | -6,467,345 | -14,228,159 | -71,140,795 |
