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 416,845, 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 | 416,845 | |
| -1 | -416,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 416,845.
Example:
1 x 416,845 = 416,845
and
-1 x -416,845 = 416,845
Notice both answers equal 416,845
With that explanation out of the way, let's continue. Next, we take the number 416,845 and divide it by 2:
416,845 ÷ 2 = 208,422.5
If the quotient is a whole number, then 2 and 208,422.5 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 | 416,845 | |
| -1 | -416,845 |
Now, we try dividing 416,845 by 3:
416,845 ÷ 3 = 138,948.3333
If the quotient is a whole number, then 3 and 138,948.3333 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 | 416,845 | |
| -1 | -416,845 |
Let's try dividing by 4:
416,845 ÷ 4 = 104,211.25
If the quotient is a whole number, then 4 and 104,211.25 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 | 416,845 | |
| -1 | 416,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 53 | 55 | 65 | 121 | 143 | 265 | 583 | 605 | 689 | 715 | 1,573 | 2,915 | 3,445 | 6,413 | 7,579 | 7,865 | 32,065 | 37,895 | 83,369 | 416,845 |
| -1 | -5 | -11 | -13 | -53 | -55 | -65 | -121 | -143 | -265 | -583 | -605 | -689 | -715 | -1,573 | -2,915 | -3,445 | -6,413 | -7,579 | -7,865 | -32,065 | -37,895 | -83,369 | -416,845 |
