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 1,613,575, 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 | 1,613,575 | |
| -1 | -1,613,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,613,575.
Example:
1 x 1,613,575 = 1,613,575
and
-1 x -1,613,575 = 1,613,575
Notice both answers equal 1,613,575
With that explanation out of the way, let's continue. Next, we take the number 1,613,575 and divide it by 2:
1,613,575 ÷ 2 = 806,787.5
If the quotient is a whole number, then 2 and 806,787.5 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 | 1,613,575 | |
| -1 | -1,613,575 |
Now, we try dividing 1,613,575 by 3:
1,613,575 ÷ 3 = 537,858.3333
If the quotient is a whole number, then 3 and 537,858.3333 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 | 1,613,575 | |
| -1 | -1,613,575 |
Let's try dividing by 4:
1,613,575 ÷ 4 = 403,393.75
If the quotient is a whole number, then 4 and 403,393.75 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 | 1,613,575 | |
| -1 | 1,613,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 43 | 79 | 95 | 215 | 395 | 475 | 817 | 1,075 | 1,501 | 1,975 | 3,397 | 4,085 | 7,505 | 16,985 | 20,425 | 37,525 | 64,543 | 84,925 | 322,715 | 1,613,575 |
| -1 | -5 | -19 | -25 | -43 | -79 | -95 | -215 | -395 | -475 | -817 | -1,075 | -1,501 | -1,975 | -3,397 | -4,085 | -7,505 | -16,985 | -20,425 | -37,525 | -64,543 | -84,925 | -322,715 | -1,613,575 |
