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 2,716,025, 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 | 2,716,025 | |
| -1 | -2,716,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,716,025.
Example:
1 x 2,716,025 = 2,716,025
and
-1 x -2,716,025 = 2,716,025
Notice both answers equal 2,716,025
With that explanation out of the way, let's continue. Next, we take the number 2,716,025 and divide it by 2:
2,716,025 ÷ 2 = 1,358,012.5
If the quotient is a whole number, then 2 and 1,358,012.5 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 | 2,716,025 | |
| -1 | -2,716,025 |
Now, we try dividing 2,716,025 by 3:
2,716,025 ÷ 3 = 905,341.6667
If the quotient is a whole number, then 3 and 905,341.6667 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 | 2,716,025 | |
| -1 | -2,716,025 |
Let's try dividing by 4:
2,716,025 ÷ 4 = 679,006.25
If the quotient is a whole number, then 4 and 679,006.25 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 | 2,716,025 | |
| -1 | 2,716,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 61 | 65 | 137 | 305 | 325 | 685 | 793 | 1,525 | 1,781 | 3,425 | 3,965 | 8,357 | 8,905 | 19,825 | 41,785 | 44,525 | 108,641 | 208,925 | 543,205 | 2,716,025 |
| -1 | -5 | -13 | -25 | -61 | -65 | -137 | -305 | -325 | -685 | -793 | -1,525 | -1,781 | -3,425 | -3,965 | -8,357 | -8,905 | -19,825 | -41,785 | -44,525 | -108,641 | -208,925 | -543,205 | -2,716,025 |
