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 1,510,465, 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 | 1,510,465 | |
| -1 | -1,510,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,510,465.
Example:
1 x 1,510,465 = 1,510,465
and
-1 x -1,510,465 = 1,510,465
Notice both answers equal 1,510,465
With that explanation out of the way, let's continue. Next, we take the number 1,510,465 and divide it by 2:
1,510,465 ÷ 2 = 755,232.5
If the quotient is a whole number, then 2 and 755,232.5 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 | 1,510,465 | |
| -1 | -1,510,465 |
Now, we try dividing 1,510,465 by 3:
1,510,465 ÷ 3 = 503,488.3333
If the quotient is a whole number, then 3 and 503,488.3333 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 | 1,510,465 | |
| -1 | -1,510,465 |
Let's try dividing by 4:
1,510,465 ÷ 4 = 377,616.25
If the quotient is a whole number, then 4 and 377,616.25 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 | 1,510,465 | |
| -1 | 1,510,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 947 | 1,595 | 4,735 | 10,417 | 27,463 | 52,085 | 137,315 | 302,093 | 1,510,465 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -947 | -1,595 | -4,735 | -10,417 | -27,463 | -52,085 | -137,315 | -302,093 | -1,510,465 |
