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 2,328,025, 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 | 2,328,025 | |
| -1 | -2,328,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,328,025.
Example:
1 x 2,328,025 = 2,328,025
and
-1 x -2,328,025 = 2,328,025
Notice both answers equal 2,328,025
With that explanation out of the way, let's continue. Next, we take the number 2,328,025 and divide it by 2:
2,328,025 ÷ 2 = 1,164,012.5
If the quotient is a whole number, then 2 and 1,164,012.5 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 | 2,328,025 | |
| -1 | -2,328,025 |
Now, we try dividing 2,328,025 by 3:
2,328,025 ÷ 3 = 776,008.3333
If the quotient is a whole number, then 3 and 776,008.3333 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 | 2,328,025 | |
| -1 | -2,328,025 |
Let's try dividing by 4:
2,328,025 ÷ 4 = 582,006.25
If the quotient is a whole number, then 4 and 582,006.25 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 | 2,328,025 | |
| -1 | 2,328,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 53 | 175 | 251 | 265 | 371 | 1,255 | 1,325 | 1,757 | 1,855 | 6,275 | 8,785 | 9,275 | 13,303 | 43,925 | 66,515 | 93,121 | 332,575 | 465,605 | 2,328,025 |
| -1 | -5 | -7 | -25 | -35 | -53 | -175 | -251 | -265 | -371 | -1,255 | -1,325 | -1,757 | -1,855 | -6,275 | -8,785 | -9,275 | -13,303 | -43,925 | -66,515 | -93,121 | -332,575 | -465,605 | -2,328,025 |
