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 7,853,575, 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 | 7,853,575 | |
| -1 | -7,853,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,853,575.
Example:
1 x 7,853,575 = 7,853,575
and
-1 x -7,853,575 = 7,853,575
Notice both answers equal 7,853,575
With that explanation out of the way, let's continue. Next, we take the number 7,853,575 and divide it by 2:
7,853,575 ÷ 2 = 3,926,787.5
If the quotient is a whole number, then 2 and 3,926,787.5 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 | 7,853,575 | |
| -1 | -7,853,575 |
Now, we try dividing 7,853,575 by 3:
7,853,575 ÷ 3 = 2,617,858.3333
If the quotient is a whole number, then 3 and 2,617,858.3333 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 | 7,853,575 | |
| -1 | -7,853,575 |
Let's try dividing by 4:
7,853,575 ÷ 4 = 1,963,393.75
If the quotient is a whole number, then 4 and 1,963,393.75 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 | 7,853,575 | |
| -1 | 7,853,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 289 | 425 | 1,087 | 1,445 | 5,435 | 7,225 | 18,479 | 27,175 | 92,395 | 314,143 | 461,975 | 1,570,715 | 7,853,575 |
| -1 | -5 | -17 | -25 | -85 | -289 | -425 | -1,087 | -1,445 | -5,435 | -7,225 | -18,479 | -27,175 | -92,395 | -314,143 | -461,975 | -1,570,715 | -7,853,575 |
