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 1,021,475, 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 | 1,021,475 | |
| -1 | -1,021,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,021,475.
Example:
1 x 1,021,475 = 1,021,475
and
-1 x -1,021,475 = 1,021,475
Notice both answers equal 1,021,475
With that explanation out of the way, let's continue. Next, we take the number 1,021,475 and divide it by 2:
1,021,475 ÷ 2 = 510,737.5
If the quotient is a whole number, then 2 and 510,737.5 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 | 1,021,475 | |
| -1 | -1,021,475 |
Now, we try dividing 1,021,475 by 3:
1,021,475 ÷ 3 = 340,491.6667
If the quotient is a whole number, then 3 and 340,491.6667 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 | 1,021,475 | |
| -1 | -1,021,475 |
Let's try dividing by 4:
1,021,475 ÷ 4 = 255,368.75
If the quotient is a whole number, then 4 and 255,368.75 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 | 1,021,475 | |
| -1 | 1,021,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 449 | 455 | 2,245 | 2,275 | 3,143 | 5,837 | 11,225 | 15,715 | 29,185 | 40,859 | 78,575 | 145,925 | 204,295 | 1,021,475 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -449 | -455 | -2,245 | -2,275 | -3,143 | -5,837 | -11,225 | -15,715 | -29,185 | -40,859 | -78,575 | -145,925 | -204,295 | -1,021,475 |
