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 71,604,451, 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 | 71,604,451 | |
| -1 | -71,604,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,604,451.
Example:
1 x 71,604,451 = 71,604,451
and
-1 x -71,604,451 = 71,604,451
Notice both answers equal 71,604,451
With that explanation out of the way, let's continue. Next, we take the number 71,604,451 and divide it by 2:
71,604,451 ÷ 2 = 35,802,225.5
If the quotient is a whole number, then 2 and 35,802,225.5 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 | 71,604,451 | |
| -1 | -71,604,451 |
Now, we try dividing 71,604,451 by 3:
71,604,451 ÷ 3 = 23,868,150.3333
If the quotient is a whole number, then 3 and 23,868,150.3333 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 | 71,604,451 | |
| -1 | -71,604,451 |
Let's try dividing by 4:
71,604,451 ÷ 4 = 17,901,112.75
If the quotient is a whole number, then 4 and 17,901,112.75 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 | 71,604,451 | |
| -1 | 71,604,451 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 31 | 667 | 713 | 899 | 3,463 | 20,677 | 79,649 | 100,427 | 107,353 | 2,309,821 | 2,469,119 | 3,113,237 | 71,604,451 |
| -1 | -23 | -29 | -31 | -667 | -713 | -899 | -3,463 | -20,677 | -79,649 | -100,427 | -107,353 | -2,309,821 | -2,469,119 | -3,113,237 | -71,604,451 |
