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 75,106,715, 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 | 75,106,715 | |
| -1 | -75,106,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,106,715.
Example:
1 x 75,106,715 = 75,106,715
and
-1 x -75,106,715 = 75,106,715
Notice both answers equal 75,106,715
With that explanation out of the way, let's continue. Next, we take the number 75,106,715 and divide it by 2:
75,106,715 ÷ 2 = 37,553,357.5
If the quotient is a whole number, then 2 and 37,553,357.5 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 | 75,106,715 | |
| -1 | -75,106,715 |
Now, we try dividing 75,106,715 by 3:
75,106,715 ÷ 3 = 25,035,571.6667
If the quotient is a whole number, then 3 and 25,035,571.6667 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 | 75,106,715 | |
| -1 | -75,106,715 |
Let's try dividing by 4:
75,106,715 ÷ 4 = 18,776,678.75
If the quotient is a whole number, then 4 and 18,776,678.75 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 | 75,106,715 | |
| -1 | 75,106,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 409 | 1,933 | 2,045 | 7,771 | 9,665 | 36,727 | 38,855 | 183,635 | 790,597 | 3,952,985 | 15,021,343 | 75,106,715 |
| -1 | -5 | -19 | -95 | -409 | -1,933 | -2,045 | -7,771 | -9,665 | -36,727 | -38,855 | -183,635 | -790,597 | -3,952,985 | -15,021,343 | -75,106,715 |
