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 7,757,575, 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 | 7,757,575 | |
| -1 | -7,757,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,757,575.
Example:
1 x 7,757,575 = 7,757,575
and
-1 x -7,757,575 = 7,757,575
Notice both answers equal 7,757,575
With that explanation out of the way, let's continue. Next, we take the number 7,757,575 and divide it by 2:
7,757,575 ÷ 2 = 3,878,787.5
If the quotient is a whole number, then 2 and 3,878,787.5 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 | 7,757,575 | |
| -1 | -7,757,575 |
Now, we try dividing 7,757,575 by 3:
7,757,575 ÷ 3 = 2,585,858.3333
If the quotient is a whole number, then 3 and 2,585,858.3333 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 | 7,757,575 | |
| -1 | -7,757,575 |
Let's try dividing by 4:
7,757,575 ÷ 4 = 1,939,393.75
If the quotient is a whole number, then 4 and 1,939,393.75 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 | 7,757,575 | |
| -1 | 7,757,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 97 | 175 | 457 | 485 | 679 | 2,285 | 2,425 | 3,199 | 3,395 | 11,425 | 15,995 | 16,975 | 44,329 | 79,975 | 221,645 | 310,303 | 1,108,225 | 1,551,515 | 7,757,575 |
| -1 | -5 | -7 | -25 | -35 | -97 | -175 | -457 | -485 | -679 | -2,285 | -2,425 | -3,199 | -3,395 | -11,425 | -15,995 | -16,975 | -44,329 | -79,975 | -221,645 | -310,303 | -1,108,225 | -1,551,515 | -7,757,575 |
