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 2,349,025, 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 | 2,349,025 | |
| -1 | -2,349,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,349,025.
Example:
1 x 2,349,025 = 2,349,025
and
-1 x -2,349,025 = 2,349,025
Notice both answers equal 2,349,025
With that explanation out of the way, let's continue. Next, we take the number 2,349,025 and divide it by 2:
2,349,025 ÷ 2 = 1,174,512.5
If the quotient is a whole number, then 2 and 1,174,512.5 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 | 2,349,025 | |
| -1 | -2,349,025 |
Now, we try dividing 2,349,025 by 3:
2,349,025 ÷ 3 = 783,008.3333
If the quotient is a whole number, then 3 and 783,008.3333 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 | 2,349,025 | |
| -1 | -2,349,025 |
Let's try dividing by 4:
2,349,025 ÷ 4 = 587,256.25
If the quotient is a whole number, then 4 and 587,256.25 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 | 2,349,025 | |
| -1 | 2,349,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 433 | 775 | 1,085 | 2,165 | 3,031 | 5,425 | 10,825 | 13,423 | 15,155 | 67,115 | 75,775 | 93,961 | 335,575 | 469,805 | 2,349,025 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -433 | -775 | -1,085 | -2,165 | -3,031 | -5,425 | -10,825 | -13,423 | -15,155 | -67,115 | -75,775 | -93,961 | -335,575 | -469,805 | -2,349,025 |
