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 7,754,165, 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 | 7,754,165 | |
| -1 | -7,754,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,754,165.
Example:
1 x 7,754,165 = 7,754,165
and
-1 x -7,754,165 = 7,754,165
Notice both answers equal 7,754,165
With that explanation out of the way, let's continue. Next, we take the number 7,754,165 and divide it by 2:
7,754,165 ÷ 2 = 3,877,082.5
If the quotient is a whole number, then 2 and 3,877,082.5 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 | 7,754,165 | |
| -1 | -7,754,165 |
Now, we try dividing 7,754,165 by 3:
7,754,165 ÷ 3 = 2,584,721.6667
If the quotient is a whole number, then 3 and 2,584,721.6667 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 | 7,754,165 | |
| -1 | -7,754,165 |
Let's try dividing by 4:
7,754,165 ÷ 4 = 1,938,541.25
If the quotient is a whole number, then 4 and 1,938,541.25 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 | 7,754,165 | |
| -1 | 7,754,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,009 | 1,537 | 5,045 | 7,685 | 29,261 | 53,477 | 146,305 | 267,385 | 1,550,833 | 7,754,165 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,009 | -1,537 | -5,045 | -7,685 | -29,261 | -53,477 | -146,305 | -267,385 | -1,550,833 | -7,754,165 |
