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 2,458,465, 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 | 2,458,465 | |
| -1 | -2,458,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,458,465.
Example:
1 x 2,458,465 = 2,458,465
and
-1 x -2,458,465 = 2,458,465
Notice both answers equal 2,458,465
With that explanation out of the way, let's continue. Next, we take the number 2,458,465 and divide it by 2:
2,458,465 ÷ 2 = 1,229,232.5
If the quotient is a whole number, then 2 and 1,229,232.5 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 | 2,458,465 | |
| -1 | -2,458,465 |
Now, we try dividing 2,458,465 by 3:
2,458,465 ÷ 3 = 819,488.3333
If the quotient is a whole number, then 3 and 819,488.3333 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 | 2,458,465 | |
| -1 | -2,458,465 |
Let's try dividing by 4:
2,458,465 ÷ 4 = 614,616.25
If the quotient is a whole number, then 4 and 614,616.25 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 | 2,458,465 | |
| -1 | 2,458,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 97 | 137 | 185 | 485 | 685 | 3,589 | 5,069 | 13,289 | 17,945 | 25,345 | 66,445 | 491,693 | 2,458,465 |
| -1 | -5 | -37 | -97 | -137 | -185 | -485 | -685 | -3,589 | -5,069 | -13,289 | -17,945 | -25,345 | -66,445 | -491,693 | -2,458,465 |
