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 4,151,329, 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 | 4,151,329 | |
| -1 | -4,151,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,151,329.
Example:
1 x 4,151,329 = 4,151,329
and
-1 x -4,151,329 = 4,151,329
Notice both answers equal 4,151,329
With that explanation out of the way, let's continue. Next, we take the number 4,151,329 and divide it by 2:
4,151,329 ÷ 2 = 2,075,664.5
If the quotient is a whole number, then 2 and 2,075,664.5 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 | 4,151,329 | |
| -1 | -4,151,329 |
Now, we try dividing 4,151,329 by 3:
4,151,329 ÷ 3 = 1,383,776.3333
If the quotient is a whole number, then 3 and 1,383,776.3333 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 | 4,151,329 | |
| -1 | -4,151,329 |
Let's try dividing by 4:
4,151,329 ÷ 4 = 1,037,832.25
If the quotient is a whole number, then 4 and 1,037,832.25 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 | 4,151,329 | |
| -1 | 4,151,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 49 | 91 | 133 | 247 | 343 | 637 | 931 | 1,729 | 2,401 | 4,459 | 6,517 | 12,103 | 16,807 | 31,213 | 45,619 | 84,721 | 218,491 | 319,333 | 593,047 | 4,151,329 |
| -1 | -7 | -13 | -19 | -49 | -91 | -133 | -247 | -343 | -637 | -931 | -1,729 | -2,401 | -4,459 | -6,517 | -12,103 | -16,807 | -31,213 | -45,619 | -84,721 | -218,491 | -319,333 | -593,047 | -4,151,329 |
