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 368,415,271, 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 | 368,415,271 | |
| -1 | -368,415,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 368,415,271.
Example:
1 x 368,415,271 = 368,415,271
and
-1 x -368,415,271 = 368,415,271
Notice both answers equal 368,415,271
With that explanation out of the way, let's continue. Next, we take the number 368,415,271 and divide it by 2:
368,415,271 ÷ 2 = 184,207,635.5
If the quotient is a whole number, then 2 and 184,207,635.5 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 | 368,415,271 | |
| -1 | -368,415,271 |
Now, we try dividing 368,415,271 by 3:
368,415,271 ÷ 3 = 122,805,090.3333
If the quotient is a whole number, then 3 and 122,805,090.3333 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 | 368,415,271 | |
| -1 | -368,415,271 |
Let's try dividing by 4:
368,415,271 ÷ 4 = 92,103,817.75
If the quotient is a whole number, then 4 and 92,103,817.75 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 | 368,415,271 | |
| -1 | 368,415,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 301 | 343 | 2,107 | 14,749 | 24,979 | 174,853 | 1,074,097 | 1,223,971 | 7,518,679 | 8,567,797 | 52,630,753 | 368,415,271 |
| -1 | -7 | -43 | -49 | -301 | -343 | -2,107 | -14,749 | -24,979 | -174,853 | -1,074,097 | -1,223,971 | -7,518,679 | -8,567,797 | -52,630,753 | -368,415,271 |
