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 1,874,719, 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 | 1,874,719 | |
| -1 | -1,874,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,874,719.
Example:
1 x 1,874,719 = 1,874,719
and
-1 x -1,874,719 = 1,874,719
Notice both answers equal 1,874,719
With that explanation out of the way, let's continue. Next, we take the number 1,874,719 and divide it by 2:
1,874,719 ÷ 2 = 937,359.5
If the quotient is a whole number, then 2 and 937,359.5 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 | 1,874,719 | |
| -1 | -1,874,719 |
Now, we try dividing 1,874,719 by 3:
1,874,719 ÷ 3 = 624,906.3333
If the quotient is a whole number, then 3 and 624,906.3333 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 | 1,874,719 | |
| -1 | -1,874,719 |
Let's try dividing by 4:
1,874,719 ÷ 4 = 468,679.75
If the quotient is a whole number, then 4 and 468,679.75 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 | 1,874,719 | |
| -1 | 1,874,719 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 251 | 679 | 1,067 | 1,757 | 2,761 | 7,469 | 19,327 | 24,347 | 170,429 | 267,817 | 1,874,719 |
| -1 | -7 | -11 | -77 | -97 | -251 | -679 | -1,067 | -1,757 | -2,761 | -7,469 | -19,327 | -24,347 | -170,429 | -267,817 | -1,874,719 |
