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 3,101,525, 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 | 3,101,525 | |
| -1 | -3,101,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,101,525.
Example:
1 x 3,101,525 = 3,101,525
and
-1 x -3,101,525 = 3,101,525
Notice both answers equal 3,101,525
With that explanation out of the way, let's continue. Next, we take the number 3,101,525 and divide it by 2:
3,101,525 ÷ 2 = 1,550,762.5
If the quotient is a whole number, then 2 and 1,550,762.5 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 | 3,101,525 | |
| -1 | -3,101,525 |
Now, we try dividing 3,101,525 by 3:
3,101,525 ÷ 3 = 1,033,841.6667
If the quotient is a whole number, then 3 and 1,033,841.6667 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 | 3,101,525 | |
| -1 | -3,101,525 |
Let's try dividing by 4:
3,101,525 ÷ 4 = 775,381.25
If the quotient is a whole number, then 4 and 775,381.25 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 | 3,101,525 | |
| -1 | 3,101,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 37 | 175 | 185 | 259 | 479 | 925 | 1,295 | 2,395 | 3,353 | 6,475 | 11,975 | 16,765 | 17,723 | 83,825 | 88,615 | 124,061 | 443,075 | 620,305 | 3,101,525 |
| -1 | -5 | -7 | -25 | -35 | -37 | -175 | -185 | -259 | -479 | -925 | -1,295 | -2,395 | -3,353 | -6,475 | -11,975 | -16,765 | -17,723 | -83,825 | -88,615 | -124,061 | -443,075 | -620,305 | -3,101,525 |
