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 1,543,645, 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 | 1,543,645 | |
| -1 | -1,543,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,543,645.
Example:
1 x 1,543,645 = 1,543,645
and
-1 x -1,543,645 = 1,543,645
Notice both answers equal 1,543,645
With that explanation out of the way, let's continue. Next, we take the number 1,543,645 and divide it by 2:
1,543,645 ÷ 2 = 771,822.5
If the quotient is a whole number, then 2 and 771,822.5 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 | 1,543,645 | |
| -1 | -1,543,645 |
Now, we try dividing 1,543,645 by 3:
1,543,645 ÷ 3 = 514,548.3333
If the quotient is a whole number, then 3 and 514,548.3333 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 | 1,543,645 | |
| -1 | -1,543,645 |
Let's try dividing by 4:
1,543,645 ÷ 4 = 385,911.25
If the quotient is a whole number, then 4 and 385,911.25 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 | 1,543,645 | |
| -1 | 1,543,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 31 | 115 | 155 | 433 | 713 | 2,165 | 3,565 | 9,959 | 13,423 | 49,795 | 67,115 | 308,729 | 1,543,645 |
| -1 | -5 | -23 | -31 | -115 | -155 | -433 | -713 | -2,165 | -3,565 | -9,959 | -13,423 | -49,795 | -67,115 | -308,729 | -1,543,645 |
