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 71,234,125, 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 | 71,234,125 | |
| -1 | -71,234,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,234,125.
Example:
1 x 71,234,125 = 71,234,125
and
-1 x -71,234,125 = 71,234,125
Notice both answers equal 71,234,125
With that explanation out of the way, let's continue. Next, we take the number 71,234,125 and divide it by 2:
71,234,125 ÷ 2 = 35,617,062.5
If the quotient is a whole number, then 2 and 35,617,062.5 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 | 71,234,125 | |
| -1 | -71,234,125 |
Now, we try dividing 71,234,125 by 3:
71,234,125 ÷ 3 = 23,744,708.3333
If the quotient is a whole number, then 3 and 23,744,708.3333 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 | 71,234,125 | |
| -1 | -71,234,125 |
Let's try dividing by 4:
71,234,125 ÷ 4 = 17,808,531.25
If the quotient is a whole number, then 4 and 17,808,531.25 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 | 71,234,125 | |
| -1 | 71,234,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 125 | 155 | 593 | 775 | 961 | 2,965 | 3,875 | 4,805 | 14,825 | 18,383 | 24,025 | 74,125 | 91,915 | 120,125 | 459,575 | 569,873 | 2,297,875 | 2,849,365 | 14,246,825 | 71,234,125 |
| -1 | -5 | -25 | -31 | -125 | -155 | -593 | -775 | -961 | -2,965 | -3,875 | -4,805 | -14,825 | -18,383 | -24,025 | -74,125 | -91,915 | -120,125 | -459,575 | -569,873 | -2,297,875 | -2,849,365 | -14,246,825 | -71,234,125 |
