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 1,849,175, 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 | 1,849,175 | |
| -1 | -1,849,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,849,175.
Example:
1 x 1,849,175 = 1,849,175
and
-1 x -1,849,175 = 1,849,175
Notice both answers equal 1,849,175
With that explanation out of the way, let's continue. Next, we take the number 1,849,175 and divide it by 2:
1,849,175 ÷ 2 = 924,587.5
If the quotient is a whole number, then 2 and 924,587.5 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 | 1,849,175 | |
| -1 | -1,849,175 |
Now, we try dividing 1,849,175 by 3:
1,849,175 ÷ 3 = 616,391.6667
If the quotient is a whole number, then 3 and 616,391.6667 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 | 1,849,175 | |
| -1 | -1,849,175 |
Let's try dividing by 4:
1,849,175 ÷ 4 = 462,293.75
If the quotient is a whole number, then 4 and 462,293.75 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 | 1,849,175 | |
| -1 | 1,849,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 25 | 85 | 95 | 229 | 323 | 425 | 475 | 1,145 | 1,615 | 3,893 | 4,351 | 5,725 | 8,075 | 19,465 | 21,755 | 73,967 | 97,325 | 108,775 | 369,835 | 1,849,175 |
| -1 | -5 | -17 | -19 | -25 | -85 | -95 | -229 | -323 | -425 | -475 | -1,145 | -1,615 | -3,893 | -4,351 | -5,725 | -8,075 | -19,465 | -21,755 | -73,967 | -97,325 | -108,775 | -369,835 | -1,849,175 |
