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 612,136,735, 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 | 612,136,735 | |
| -1 | -612,136,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,136,735.
Example:
1 x 612,136,735 = 612,136,735
and
-1 x -612,136,735 = 612,136,735
Notice both answers equal 612,136,735
With that explanation out of the way, let's continue. Next, we take the number 612,136,735 and divide it by 2:
612,136,735 ÷ 2 = 306,068,367.5
If the quotient is a whole number, then 2 and 306,068,367.5 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 | 612,136,735 | |
| -1 | -612,136,735 |
Now, we try dividing 612,136,735 by 3:
612,136,735 ÷ 3 = 204,045,578.3333
If the quotient is a whole number, then 3 and 204,045,578.3333 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 | 612,136,735 | |
| -1 | -612,136,735 |
Let's try dividing by 4:
612,136,735 ÷ 4 = 153,034,183.75
If the quotient is a whole number, then 4 and 153,034,183.75 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 | 612,136,735 | |
| -1 | 612,136,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 257 | 1,285 | 1,799 | 8,995 | 68,053 | 340,265 | 476,371 | 2,381,855 | 17,489,621 | 87,448,105 | 122,427,347 | 612,136,735 |
| -1 | -5 | -7 | -35 | -257 | -1,285 | -1,799 | -8,995 | -68,053 | -340,265 | -476,371 | -2,381,855 | -17,489,621 | -87,448,105 | -122,427,347 | -612,136,735 |
