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 1,314,775, 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 | 1,314,775 | |
| -1 | -1,314,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,314,775.
Example:
1 x 1,314,775 = 1,314,775
and
-1 x -1,314,775 = 1,314,775
Notice both answers equal 1,314,775
With that explanation out of the way, let's continue. Next, we take the number 1,314,775 and divide it by 2:
1,314,775 ÷ 2 = 657,387.5
If the quotient is a whole number, then 2 and 657,387.5 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 | 1,314,775 | |
| -1 | -1,314,775 |
Now, we try dividing 1,314,775 by 3:
1,314,775 ÷ 3 = 438,258.3333
If the quotient is a whole number, then 3 and 438,258.3333 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 | 1,314,775 | |
| -1 | -1,314,775 |
Let's try dividing by 4:
1,314,775 ÷ 4 = 328,693.75
If the quotient is a whole number, then 4 and 328,693.75 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 | 1,314,775 | |
| -1 | 1,314,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 683 | 1,925 | 3,415 | 4,781 | 7,513 | 17,075 | 23,905 | 37,565 | 52,591 | 119,525 | 187,825 | 262,955 | 1,314,775 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -683 | -1,925 | -3,415 | -4,781 | -7,513 | -17,075 | -23,905 | -37,565 | -52,591 | -119,525 | -187,825 | -262,955 | -1,314,775 |
