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 103,151,335, 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 | 103,151,335 | |
| -1 | -103,151,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,151,335.
Example:
1 x 103,151,335 = 103,151,335
and
-1 x -103,151,335 = 103,151,335
Notice both answers equal 103,151,335
With that explanation out of the way, let's continue. Next, we take the number 103,151,335 and divide it by 2:
103,151,335 ÷ 2 = 51,575,667.5
If the quotient is a whole number, then 2 and 51,575,667.5 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 | 103,151,335 | |
| -1 | -103,151,335 |
Now, we try dividing 103,151,335 by 3:
103,151,335 ÷ 3 = 34,383,778.3333
If the quotient is a whole number, then 3 and 34,383,778.3333 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 | 103,151,335 | |
| -1 | -103,151,335 |
Let's try dividing by 4:
103,151,335 ÷ 4 = 25,787,833.75
If the quotient is a whole number, then 4 and 25,787,833.75 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 | 103,151,335 | |
| -1 | 103,151,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 719 | 3,595 | 4,099 | 5,033 | 20,495 | 25,165 | 28,693 | 143,465 | 2,947,181 | 14,735,905 | 20,630,267 | 103,151,335 |
| -1 | -5 | -7 | -35 | -719 | -3,595 | -4,099 | -5,033 | -20,495 | -25,165 | -28,693 | -143,465 | -2,947,181 | -14,735,905 | -20,630,267 | -103,151,335 |
