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 5,781,469, 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 | 5,781,469 | |
| -1 | -5,781,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,781,469.
Example:
1 x 5,781,469 = 5,781,469
and
-1 x -5,781,469 = 5,781,469
Notice both answers equal 5,781,469
With that explanation out of the way, let's continue. Next, we take the number 5,781,469 and divide it by 2:
5,781,469 ÷ 2 = 2,890,734.5
If the quotient is a whole number, then 2 and 2,890,734.5 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 | 5,781,469 | |
| -1 | -5,781,469 |
Now, we try dividing 5,781,469 by 3:
5,781,469 ÷ 3 = 1,927,156.3333
If the quotient is a whole number, then 3 and 1,927,156.3333 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 | 5,781,469 | |
| -1 | -5,781,469 |
Let's try dividing by 4:
5,781,469 ÷ 4 = 1,445,367.25
If the quotient is a whole number, then 4 and 1,445,367.25 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 | 5,781,469 | |
| -1 | 5,781,469 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 59 | 109 | 899 | 1,711 | 1,829 | 3,161 | 3,379 | 6,431 | 53,041 | 97,991 | 186,499 | 199,361 | 5,781,469 |
| -1 | -29 | -31 | -59 | -109 | -899 | -1,711 | -1,829 | -3,161 | -3,379 | -6,431 | -53,041 | -97,991 | -186,499 | -199,361 | -5,781,469 |
