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 1,252,097, 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 | 1,252,097 | |
| -1 | -1,252,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,252,097.
Example:
1 x 1,252,097 = 1,252,097
and
-1 x -1,252,097 = 1,252,097
Notice both answers equal 1,252,097
With that explanation out of the way, let's continue. Next, we take the number 1,252,097 and divide it by 2:
1,252,097 ÷ 2 = 626,048.5
If the quotient is a whole number, then 2 and 626,048.5 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 | 1,252,097 | |
| -1 | -1,252,097 |
Now, we try dividing 1,252,097 by 3:
1,252,097 ÷ 3 = 417,365.6667
If the quotient is a whole number, then 3 and 417,365.6667 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 | 1,252,097 | |
| -1 | -1,252,097 |
Let's try dividing by 4:
1,252,097 ÷ 4 = 313,024.25
If the quotient is a whole number, then 4 and 313,024.25 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 | 1,252,097 | |
| -1 | 1,252,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 49 | 77 | 101 | 161 | 253 | 539 | 707 | 1,111 | 1,127 | 1,771 | 2,323 | 4,949 | 7,777 | 12,397 | 16,261 | 25,553 | 54,439 | 113,827 | 178,871 | 1,252,097 |
| -1 | -7 | -11 | -23 | -49 | -77 | -101 | -161 | -253 | -539 | -707 | -1,111 | -1,127 | -1,771 | -2,323 | -4,949 | -7,777 | -12,397 | -16,261 | -25,553 | -54,439 | -113,827 | -178,871 | -1,252,097 |
