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 1,642,501, 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 | 1,642,501 | |
| -1 | -1,642,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,642,501.
Example:
1 x 1,642,501 = 1,642,501
and
-1 x -1,642,501 = 1,642,501
Notice both answers equal 1,642,501
With that explanation out of the way, let's continue. Next, we take the number 1,642,501 and divide it by 2:
1,642,501 ÷ 2 = 821,250.5
If the quotient is a whole number, then 2 and 821,250.5 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 | 1,642,501 | |
| -1 | -1,642,501 |
Now, we try dividing 1,642,501 by 3:
1,642,501 ÷ 3 = 547,500.3333
If the quotient is a whole number, then 3 and 547,500.3333 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 | 1,642,501 | |
| -1 | -1,642,501 |
Let's try dividing by 4:
1,642,501 ÷ 4 = 410,625.25
If the quotient is a whole number, then 4 and 410,625.25 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 | 1,642,501 | |
| -1 | 1,642,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 59 | 97 | 287 | 413 | 679 | 2,419 | 3,977 | 5,723 | 16,933 | 27,839 | 40,061 | 234,643 | 1,642,501 |
| -1 | -7 | -41 | -59 | -97 | -287 | -413 | -679 | -2,419 | -3,977 | -5,723 | -16,933 | -27,839 | -40,061 | -234,643 | -1,642,501 |
