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 71,211,469, 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 | 71,211,469 | |
| -1 | -71,211,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,211,469.
Example:
1 x 71,211,469 = 71,211,469
and
-1 x -71,211,469 = 71,211,469
Notice both answers equal 71,211,469
With that explanation out of the way, let's continue. Next, we take the number 71,211,469 and divide it by 2:
71,211,469 ÷ 2 = 35,605,734.5
If the quotient is a whole number, then 2 and 35,605,734.5 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 | 71,211,469 | |
| -1 | -71,211,469 |
Now, we try dividing 71,211,469 by 3:
71,211,469 ÷ 3 = 23,737,156.3333
If the quotient is a whole number, then 3 and 23,737,156.3333 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 | 71,211,469 | |
| -1 | -71,211,469 |
Let's try dividing by 4:
71,211,469 ÷ 4 = 17,802,867.25
If the quotient is a whole number, then 4 and 17,802,867.25 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 | 71,211,469 | |
| -1 | 71,211,469 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 131 | 553 | 917 | 983 | 6,881 | 10,349 | 72,443 | 77,657 | 128,773 | 543,599 | 901,411 | 10,173,067 | 71,211,469 |
| -1 | -7 | -79 | -131 | -553 | -917 | -983 | -6,881 | -10,349 | -72,443 | -77,657 | -128,773 | -543,599 | -901,411 | -10,173,067 | -71,211,469 |
