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 1,240,525, 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 | 1,240,525 | |
| -1 | -1,240,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,240,525.
Example:
1 x 1,240,525 = 1,240,525
and
-1 x -1,240,525 = 1,240,525
Notice both answers equal 1,240,525
With that explanation out of the way, let's continue. Next, we take the number 1,240,525 and divide it by 2:
1,240,525 ÷ 2 = 620,262.5
If the quotient is a whole number, then 2 and 620,262.5 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 | 1,240,525 | |
| -1 | -1,240,525 |
Now, we try dividing 1,240,525 by 3:
1,240,525 ÷ 3 = 413,508.3333
If the quotient is a whole number, then 3 and 413,508.3333 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 | 1,240,525 | |
| -1 | -1,240,525 |
Let's try dividing by 4:
1,240,525 ÷ 4 = 310,131.25
If the quotient is a whole number, then 4 and 310,131.25 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 | 1,240,525 | |
| -1 | 1,240,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 347 | 715 | 1,735 | 3,575 | 3,817 | 4,511 | 8,675 | 19,085 | 22,555 | 49,621 | 95,425 | 112,775 | 248,105 | 1,240,525 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -347 | -715 | -1,735 | -3,575 | -3,817 | -4,511 | -8,675 | -19,085 | -22,555 | -49,621 | -95,425 | -112,775 | -248,105 | -1,240,525 |
