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 1,673,615, 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 | 1,673,615 | |
| -1 | -1,673,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,673,615.
Example:
1 x 1,673,615 = 1,673,615
and
-1 x -1,673,615 = 1,673,615
Notice both answers equal 1,673,615
With that explanation out of the way, let's continue. Next, we take the number 1,673,615 and divide it by 2:
1,673,615 ÷ 2 = 836,807.5
If the quotient is a whole number, then 2 and 836,807.5 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 | 1,673,615 | |
| -1 | -1,673,615 |
Now, we try dividing 1,673,615 by 3:
1,673,615 ÷ 3 = 557,871.6667
If the quotient is a whole number, then 3 and 557,871.6667 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 | 1,673,615 | |
| -1 | -1,673,615 |
Let's try dividing by 4:
1,673,615 ÷ 4 = 418,403.75
If the quotient is a whole number, then 4 and 418,403.75 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 | 1,673,615 | |
| -1 | 1,673,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 79 | 95 | 223 | 395 | 1,115 | 1,501 | 4,237 | 7,505 | 17,617 | 21,185 | 88,085 | 334,723 | 1,673,615 |
| -1 | -5 | -19 | -79 | -95 | -223 | -395 | -1,115 | -1,501 | -4,237 | -7,505 | -17,617 | -21,185 | -88,085 | -334,723 | -1,673,615 |
