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 1,157,065, 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 | 1,157,065 | |
| -1 | -1,157,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,157,065.
Example:
1 x 1,157,065 = 1,157,065
and
-1 x -1,157,065 = 1,157,065
Notice both answers equal 1,157,065
With that explanation out of the way, let's continue. Next, we take the number 1,157,065 and divide it by 2:
1,157,065 ÷ 2 = 578,532.5
If the quotient is a whole number, then 2 and 578,532.5 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 | 1,157,065 | |
| -1 | -1,157,065 |
Now, we try dividing 1,157,065 by 3:
1,157,065 ÷ 3 = 385,688.3333
If the quotient is a whole number, then 3 and 385,688.3333 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 | 1,157,065 | |
| -1 | -1,157,065 |
Let's try dividing by 4:
1,157,065 ÷ 4 = 289,266.25
If the quotient is a whole number, then 4 and 289,266.25 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 | 1,157,065 | |
| -1 | 1,157,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 2,543 | 12,715 | 17,801 | 33,059 | 89,005 | 165,295 | 231,413 | 1,157,065 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -2,543 | -12,715 | -17,801 | -33,059 | -89,005 | -165,295 | -231,413 | -1,157,065 |
