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 1,457,015, 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 | 1,457,015 | |
| -1 | -1,457,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,457,015.
Example:
1 x 1,457,015 = 1,457,015
and
-1 x -1,457,015 = 1,457,015
Notice both answers equal 1,457,015
With that explanation out of the way, let's continue. Next, we take the number 1,457,015 and divide it by 2:
1,457,015 ÷ 2 = 728,507.5
If the quotient is a whole number, then 2 and 728,507.5 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 | 1,457,015 | |
| -1 | -1,457,015 |
Now, we try dividing 1,457,015 by 3:
1,457,015 ÷ 3 = 485,671.6667
If the quotient is a whole number, then 3 and 485,671.6667 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 | 1,457,015 | |
| -1 | -1,457,015 |
Let's try dividing by 4:
1,457,015 ÷ 4 = 364,253.75
If the quotient is a whole number, then 4 and 364,253.75 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 | 1,457,015 | |
| -1 | 1,457,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 313 | 665 | 931 | 1,565 | 2,191 | 4,655 | 5,947 | 10,955 | 15,337 | 29,735 | 41,629 | 76,685 | 208,145 | 291,403 | 1,457,015 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -313 | -665 | -931 | -1,565 | -2,191 | -4,655 | -5,947 | -10,955 | -15,337 | -29,735 | -41,629 | -76,685 | -208,145 | -291,403 | -1,457,015 |
