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 2,345,525, 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 | 2,345,525 | |
| -1 | -2,345,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,345,525.
Example:
1 x 2,345,525 = 2,345,525
and
-1 x -2,345,525 = 2,345,525
Notice both answers equal 2,345,525
With that explanation out of the way, let's continue. Next, we take the number 2,345,525 and divide it by 2:
2,345,525 ÷ 2 = 1,172,762.5
If the quotient is a whole number, then 2 and 1,172,762.5 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 | 2,345,525 | |
| -1 | -2,345,525 |
Now, we try dividing 2,345,525 by 3:
2,345,525 ÷ 3 = 781,841.6667
If the quotient is a whole number, then 3 and 781,841.6667 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 | 2,345,525 | |
| -1 | -2,345,525 |
Let's try dividing by 4:
2,345,525 ÷ 4 = 586,381.25
If the quotient is a whole number, then 4 and 586,381.25 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 | 2,345,525 | |
| -1 | 2,345,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 1,031 | 2,275 | 5,155 | 7,217 | 13,403 | 25,775 | 36,085 | 67,015 | 93,821 | 180,425 | 335,075 | 469,105 | 2,345,525 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -1,031 | -2,275 | -5,155 | -7,217 | -13,403 | -25,775 | -36,085 | -67,015 | -93,821 | -180,425 | -335,075 | -469,105 | -2,345,525 |
