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 7,752,311, 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 | 7,752,311 | |
| -1 | -7,752,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,752,311.
Example:
1 x 7,752,311 = 7,752,311
and
-1 x -7,752,311 = 7,752,311
Notice both answers equal 7,752,311
With that explanation out of the way, let's continue. Next, we take the number 7,752,311 and divide it by 2:
7,752,311 ÷ 2 = 3,876,155.5
If the quotient is a whole number, then 2 and 3,876,155.5 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 | 7,752,311 | |
| -1 | -7,752,311 |
Now, we try dividing 7,752,311 by 3:
7,752,311 ÷ 3 = 2,584,103.6667
If the quotient is a whole number, then 3 and 2,584,103.6667 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 | 7,752,311 | |
| -1 | -7,752,311 |
Let's try dividing by 4:
7,752,311 ÷ 4 = 1,938,077.75
If the quotient is a whole number, then 4 and 1,938,077.75 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 | 7,752,311 | |
| -1 | 7,752,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 179 | 269 | 1,253 | 1,883 | 4,117 | 6,187 | 28,819 | 43,309 | 48,151 | 337,057 | 1,107,473 | 7,752,311 |
| -1 | -7 | -23 | -161 | -179 | -269 | -1,253 | -1,883 | -4,117 | -6,187 | -28,819 | -43,309 | -48,151 | -337,057 | -1,107,473 | -7,752,311 |
