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 71,616,575, 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 | 71,616,575 | |
| -1 | -71,616,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,616,575.
Example:
1 x 71,616,575 = 71,616,575
and
-1 x -71,616,575 = 71,616,575
Notice both answers equal 71,616,575
With that explanation out of the way, let's continue. Next, we take the number 71,616,575 and divide it by 2:
71,616,575 ÷ 2 = 35,808,287.5
If the quotient is a whole number, then 2 and 35,808,287.5 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 | 71,616,575 | |
| -1 | -71,616,575 |
Now, we try dividing 71,616,575 by 3:
71,616,575 ÷ 3 = 23,872,191.6667
If the quotient is a whole number, then 3 and 23,872,191.6667 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 | 71,616,575 | |
| -1 | -71,616,575 |
Let's try dividing by 4:
71,616,575 ÷ 4 = 17,904,143.75
If the quotient is a whole number, then 4 and 17,904,143.75 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 | 71,616,575 | |
| -1 | 71,616,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 101 | 113 | 251 | 505 | 565 | 1,255 | 2,525 | 2,825 | 6,275 | 11,413 | 25,351 | 28,363 | 57,065 | 126,755 | 141,815 | 285,325 | 633,775 | 709,075 | 2,864,663 | 14,323,315 | 71,616,575 |
| -1 | -5 | -25 | -101 | -113 | -251 | -505 | -565 | -1,255 | -2,525 | -2,825 | -6,275 | -11,413 | -25,351 | -28,363 | -57,065 | -126,755 | -141,815 | -285,325 | -633,775 | -709,075 | -2,864,663 | -14,323,315 | -71,616,575 |
