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 3,556,175, 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 | 3,556,175 | |
| -1 | -3,556,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,556,175.
Example:
1 x 3,556,175 = 3,556,175
and
-1 x -3,556,175 = 3,556,175
Notice both answers equal 3,556,175
With that explanation out of the way, let's continue. Next, we take the number 3,556,175 and divide it by 2:
3,556,175 ÷ 2 = 1,778,087.5
If the quotient is a whole number, then 2 and 1,778,087.5 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 | 3,556,175 | |
| -1 | -3,556,175 |
Now, we try dividing 3,556,175 by 3:
3,556,175 ÷ 3 = 1,185,391.6667
If the quotient is a whole number, then 3 and 1,185,391.6667 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 | 3,556,175 | |
| -1 | -3,556,175 |
Let's try dividing by 4:
3,556,175 ÷ 4 = 889,043.75
If the quotient is a whole number, then 4 and 889,043.75 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 | 3,556,175 | |
| -1 | 3,556,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 2,903 | 14,515 | 20,321 | 72,575 | 101,605 | 142,247 | 508,025 | 711,235 | 3,556,175 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -2,903 | -14,515 | -20,321 | -72,575 | -101,605 | -142,247 | -508,025 | -711,235 | -3,556,175 |
