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 1,401,631, 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 | 1,401,631 | |
| -1 | -1,401,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,401,631.
Example:
1 x 1,401,631 = 1,401,631
and
-1 x -1,401,631 = 1,401,631
Notice both answers equal 1,401,631
With that explanation out of the way, let's continue. Next, we take the number 1,401,631 and divide it by 2:
1,401,631 ÷ 2 = 700,815.5
If the quotient is a whole number, then 2 and 700,815.5 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 | 1,401,631 | |
| -1 | -1,401,631 |
Now, we try dividing 1,401,631 by 3:
1,401,631 ÷ 3 = 467,210.3333
If the quotient is a whole number, then 3 and 467,210.3333 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 | 1,401,631 | |
| -1 | -1,401,631 |
Let's try dividing by 4:
1,401,631 ÷ 4 = 350,407.75
If the quotient is a whole number, then 4 and 350,407.75 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 | 1,401,631 | |
| -1 | 1,401,631 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 109 | 167 | 763 | 1,169 | 1,199 | 1,837 | 8,393 | 12,859 | 18,203 | 127,421 | 200,233 | 1,401,631 |
| -1 | -7 | -11 | -77 | -109 | -167 | -763 | -1,169 | -1,199 | -1,837 | -8,393 | -12,859 | -18,203 | -127,421 | -200,233 | -1,401,631 |
