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 75,643,469, 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 | 75,643,469 | |
| -1 | -75,643,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,643,469.
Example:
1 x 75,643,469 = 75,643,469
and
-1 x -75,643,469 = 75,643,469
Notice both answers equal 75,643,469
With that explanation out of the way, let's continue. Next, we take the number 75,643,469 and divide it by 2:
75,643,469 ÷ 2 = 37,821,734.5
If the quotient is a whole number, then 2 and 37,821,734.5 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 | 75,643,469 | |
| -1 | -75,643,469 |
Now, we try dividing 75,643,469 by 3:
75,643,469 ÷ 3 = 25,214,489.6667
If the quotient is a whole number, then 3 and 25,214,489.6667 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 | 75,643,469 | |
| -1 | -75,643,469 |
Let's try dividing by 4:
75,643,469 ÷ 4 = 18,910,867.25
If the quotient is a whole number, then 4 and 18,910,867.25 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 | 75,643,469 | |
| -1 | 75,643,469 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 197 | 521 | 737 | 2,167 | 5,731 | 13,199 | 34,907 | 102,637 | 145,189 | 383,977 | 1,129,007 | 6,876,679 | 75,643,469 |
| -1 | -11 | -67 | -197 | -521 | -737 | -2,167 | -5,731 | -13,199 | -34,907 | -102,637 | -145,189 | -383,977 | -1,129,007 | -6,876,679 | -75,643,469 |
