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 4,380,565, 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 | 4,380,565 | |
| -1 | -4,380,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,380,565.
Example:
1 x 4,380,565 = 4,380,565
and
-1 x -4,380,565 = 4,380,565
Notice both answers equal 4,380,565
With that explanation out of the way, let's continue. Next, we take the number 4,380,565 and divide it by 2:
4,380,565 ÷ 2 = 2,190,282.5
If the quotient is a whole number, then 2 and 2,190,282.5 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 | 4,380,565 | |
| -1 | -4,380,565 |
Now, we try dividing 4,380,565 by 3:
4,380,565 ÷ 3 = 1,460,188.3333
If the quotient is a whole number, then 3 and 1,460,188.3333 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 | 4,380,565 | |
| -1 | -4,380,565 |
Let's try dividing by 4:
4,380,565 ÷ 4 = 1,095,141.25
If the quotient is a whole number, then 4 and 1,095,141.25 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 | 4,380,565 | |
| -1 | 4,380,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 257 | 487 | 1,285 | 1,799 | 2,435 | 3,409 | 8,995 | 17,045 | 125,159 | 625,795 | 876,113 | 4,380,565 |
| -1 | -5 | -7 | -35 | -257 | -487 | -1,285 | -1,799 | -2,435 | -3,409 | -8,995 | -17,045 | -125,159 | -625,795 | -876,113 | -4,380,565 |
