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 368,727,107, 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 | 368,727,107 | |
| -1 | -368,727,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 368,727,107.
Example:
1 x 368,727,107 = 368,727,107
and
-1 x -368,727,107 = 368,727,107
Notice both answers equal 368,727,107
With that explanation out of the way, let's continue. Next, we take the number 368,727,107 and divide it by 2:
368,727,107 ÷ 2 = 184,363,553.5
If the quotient is a whole number, then 2 and 184,363,553.5 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 | 368,727,107 | |
| -1 | -368,727,107 |
Now, we try dividing 368,727,107 by 3:
368,727,107 ÷ 3 = 122,909,035.6667
If the quotient is a whole number, then 3 and 122,909,035.6667 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 | 368,727,107 | |
| -1 | -368,727,107 |
Let's try dividing by 4:
368,727,107 ÷ 4 = 92,181,776.75
If the quotient is a whole number, then 4 and 92,181,776.75 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 | 368,727,107 | |
| -1 | 368,727,107 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 139 | 301 | 973 | 1,259 | 2,107 | 5,977 | 6,811 | 8,813 | 41,839 | 54,137 | 61,691 | 175,001 | 292,873 | 378,959 | 1,225,007 | 2,652,713 | 7,525,043 | 8,575,049 | 52,675,301 | 368,727,107 |
| -1 | -7 | -43 | -49 | -139 | -301 | -973 | -1,259 | -2,107 | -5,977 | -6,811 | -8,813 | -41,839 | -54,137 | -61,691 | -175,001 | -292,873 | -378,959 | -1,225,007 | -2,652,713 | -7,525,043 | -8,575,049 | -52,675,301 | -368,727,107 |
