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 4,680,151, 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 | 4,680,151 | |
| -1 | -4,680,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,680,151.
Example:
1 x 4,680,151 = 4,680,151
and
-1 x -4,680,151 = 4,680,151
Notice both answers equal 4,680,151
With that explanation out of the way, let's continue. Next, we take the number 4,680,151 and divide it by 2:
4,680,151 ÷ 2 = 2,340,075.5
If the quotient is a whole number, then 2 and 2,340,075.5 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 | 4,680,151 | |
| -1 | -4,680,151 |
Now, we try dividing 4,680,151 by 3:
4,680,151 ÷ 3 = 1,560,050.3333
If the quotient is a whole number, then 3 and 1,560,050.3333 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 | 4,680,151 | |
| -1 | -4,680,151 |
Let's try dividing by 4:
4,680,151 ÷ 4 = 1,170,037.75
If the quotient is a whole number, then 4 and 1,170,037.75 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 | 4,680,151 | |
| -1 | 4,680,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 67 | 119 | 469 | 587 | 1,139 | 4,109 | 7,973 | 9,979 | 39,329 | 69,853 | 275,303 | 668,593 | 4,680,151 |
| -1 | -7 | -17 | -67 | -119 | -469 | -587 | -1,139 | -4,109 | -7,973 | -9,979 | -39,329 | -69,853 | -275,303 | -668,593 | -4,680,151 |
