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 1,372,835, 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 | 1,372,835 | |
| -1 | -1,372,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,372,835.
Example:
1 x 1,372,835 = 1,372,835
and
-1 x -1,372,835 = 1,372,835
Notice both answers equal 1,372,835
With that explanation out of the way, let's continue. Next, we take the number 1,372,835 and divide it by 2:
1,372,835 ÷ 2 = 686,417.5
If the quotient is a whole number, then 2 and 686,417.5 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 | 1,372,835 | |
| -1 | -1,372,835 |
Now, we try dividing 1,372,835 by 3:
1,372,835 ÷ 3 = 457,611.6667
If the quotient is a whole number, then 3 and 457,611.6667 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 | 1,372,835 | |
| -1 | -1,372,835 |
Let's try dividing by 4:
1,372,835 ÷ 4 = 343,208.75
If the quotient is a whole number, then 4 and 343,208.75 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 | 1,372,835 | |
| -1 | 1,372,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 521 | 527 | 2,605 | 2,635 | 8,857 | 16,151 | 44,285 | 80,755 | 274,567 | 1,372,835 |
| -1 | -5 | -17 | -31 | -85 | -155 | -521 | -527 | -2,605 | -2,635 | -8,857 | -16,151 | -44,285 | -80,755 | -274,567 | -1,372,835 |
