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 2,469,025, 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 | 2,469,025 | |
| -1 | -2,469,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,469,025.
Example:
1 x 2,469,025 = 2,469,025
and
-1 x -2,469,025 = 2,469,025
Notice both answers equal 2,469,025
With that explanation out of the way, let's continue. Next, we take the number 2,469,025 and divide it by 2:
2,469,025 ÷ 2 = 1,234,512.5
If the quotient is a whole number, then 2 and 1,234,512.5 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 | 2,469,025 | |
| -1 | -2,469,025 |
Now, we try dividing 2,469,025 by 3:
2,469,025 ÷ 3 = 823,008.3333
If the quotient is a whole number, then 3 and 823,008.3333 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 | 2,469,025 | |
| -1 | -2,469,025 |
Let's try dividing by 4:
2,469,025 ÷ 4 = 617,256.25
If the quotient is a whole number, then 4 and 617,256.25 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 | 2,469,025 | |
| -1 | 2,469,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 71 | 107 | 325 | 355 | 535 | 923 | 1,391 | 1,775 | 2,675 | 4,615 | 6,955 | 7,597 | 23,075 | 34,775 | 37,985 | 98,761 | 189,925 | 493,805 | 2,469,025 |
| -1 | -5 | -13 | -25 | -65 | -71 | -107 | -325 | -355 | -535 | -923 | -1,391 | -1,775 | -2,675 | -4,615 | -6,955 | -7,597 | -23,075 | -34,775 | -37,985 | -98,761 | -189,925 | -493,805 | -2,469,025 |
