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 612,446,555, 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 | 612,446,555 | |
| -1 | -612,446,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,446,555.
Example:
1 x 612,446,555 = 612,446,555
and
-1 x -612,446,555 = 612,446,555
Notice both answers equal 612,446,555
With that explanation out of the way, let's continue. Next, we take the number 612,446,555 and divide it by 2:
612,446,555 ÷ 2 = 306,223,277.5
If the quotient is a whole number, then 2 and 306,223,277.5 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 | 612,446,555 | |
| -1 | -612,446,555 |
Now, we try dividing 612,446,555 by 3:
612,446,555 ÷ 3 = 204,148,851.6667
If the quotient is a whole number, then 3 and 204,148,851.6667 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 | 612,446,555 | |
| -1 | -612,446,555 |
Let's try dividing by 4:
612,446,555 ÷ 4 = 153,111,638.75
If the quotient is a whole number, then 4 and 153,111,638.75 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 | 612,446,555 | |
| -1 | 612,446,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,503 | 6,991 | 12,515 | 17,521 | 34,955 | 48,937 | 87,605 | 244,685 | 17,498,473 | 87,492,365 | 122,489,311 | 612,446,555 |
| -1 | -5 | -7 | -35 | -2,503 | -6,991 | -12,515 | -17,521 | -34,955 | -48,937 | -87,605 | -244,685 | -17,498,473 | -87,492,365 | -122,489,311 | -612,446,555 |
