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 1,405,525, 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 | 1,405,525 | |
| -1 | -1,405,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,405,525.
Example:
1 x 1,405,525 = 1,405,525
and
-1 x -1,405,525 = 1,405,525
Notice both answers equal 1,405,525
With that explanation out of the way, let's continue. Next, we take the number 1,405,525 and divide it by 2:
1,405,525 ÷ 2 = 702,762.5
If the quotient is a whole number, then 2 and 702,762.5 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 | 1,405,525 | |
| -1 | -1,405,525 |
Now, we try dividing 1,405,525 by 3:
1,405,525 ÷ 3 = 468,508.3333
If the quotient is a whole number, then 3 and 468,508.3333 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 | 1,405,525 | |
| -1 | -1,405,525 |
Let's try dividing by 4:
1,405,525 ÷ 4 = 351,381.25
If the quotient is a whole number, then 4 and 351,381.25 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 | 1,405,525 | |
| -1 | 1,405,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 25 | 55 | 95 | 209 | 269 | 275 | 475 | 1,045 | 1,345 | 2,959 | 5,111 | 5,225 | 6,725 | 14,795 | 25,555 | 56,221 | 73,975 | 127,775 | 281,105 | 1,405,525 |
| -1 | -5 | -11 | -19 | -25 | -55 | -95 | -209 | -269 | -275 | -475 | -1,045 | -1,345 | -2,959 | -5,111 | -5,225 | -6,725 | -14,795 | -25,555 | -56,221 | -73,975 | -127,775 | -281,105 | -1,405,525 |
