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 75,176,969, 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 | 75,176,969 | |
| -1 | -75,176,969 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,176,969.
Example:
1 x 75,176,969 = 75,176,969
and
-1 x -75,176,969 = 75,176,969
Notice both answers equal 75,176,969
With that explanation out of the way, let's continue. Next, we take the number 75,176,969 and divide it by 2:
75,176,969 ÷ 2 = 37,588,484.5
If the quotient is a whole number, then 2 and 37,588,484.5 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 | 75,176,969 | |
| -1 | -75,176,969 |
Now, we try dividing 75,176,969 by 3:
75,176,969 ÷ 3 = 25,058,989.6667
If the quotient is a whole number, then 3 and 25,058,989.6667 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 | 75,176,969 | |
| -1 | -75,176,969 |
Let's try dividing by 4:
75,176,969 ÷ 4 = 18,794,242.25
If the quotient is a whole number, then 4 and 18,794,242.25 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 | 75,176,969 | |
| -1 | 75,176,969 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 277 | 283 | 959 | 1,939 | 1,981 | 37,949 | 38,771 | 78,391 | 265,643 | 271,397 | 548,737 | 10,739,567 | 75,176,969 |
| -1 | -7 | -137 | -277 | -283 | -959 | -1,939 | -1,981 | -37,949 | -38,771 | -78,391 | -265,643 | -271,397 | -548,737 | -10,739,567 | -75,176,969 |
