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 43,758,655, 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 | 43,758,655 | |
| -1 | -43,758,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,758,655.
Example:
1 x 43,758,655 = 43,758,655
and
-1 x -43,758,655 = 43,758,655
Notice both answers equal 43,758,655
With that explanation out of the way, let's continue. Next, we take the number 43,758,655 and divide it by 2:
43,758,655 ÷ 2 = 21,879,327.5
If the quotient is a whole number, then 2 and 21,879,327.5 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 | 43,758,655 | |
| -1 | -43,758,655 |
Now, we try dividing 43,758,655 by 3:
43,758,655 ÷ 3 = 14,586,218.3333
If the quotient is a whole number, then 3 and 14,586,218.3333 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 | 43,758,655 | |
| -1 | -43,758,655 |
Let's try dividing by 4:
43,758,655 ÷ 4 = 10,939,663.75
If the quotient is a whole number, then 4 and 10,939,663.75 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 | 43,758,655 | |
| -1 | 43,758,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 61 | 265 | 305 | 2,707 | 3,233 | 13,535 | 16,165 | 143,471 | 165,127 | 717,355 | 825,635 | 8,751,731 | 43,758,655 |
| -1 | -5 | -53 | -61 | -265 | -305 | -2,707 | -3,233 | -13,535 | -16,165 | -143,471 | -165,127 | -717,355 | -825,635 | -8,751,731 | -43,758,655 |
