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 4,665,143, 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 | 4,665,143 | |
| -1 | -4,665,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,665,143.
Example:
1 x 4,665,143 = 4,665,143
and
-1 x -4,665,143 = 4,665,143
Notice both answers equal 4,665,143
With that explanation out of the way, let's continue. Next, we take the number 4,665,143 and divide it by 2:
4,665,143 ÷ 2 = 2,332,571.5
If the quotient is a whole number, then 2 and 2,332,571.5 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 | 4,665,143 | |
| -1 | -4,665,143 |
Now, we try dividing 4,665,143 by 3:
4,665,143 ÷ 3 = 1,555,047.6667
If the quotient is a whole number, then 3 and 1,555,047.6667 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 | 4,665,143 | |
| -1 | -4,665,143 |
Let's try dividing by 4:
4,665,143 ÷ 4 = 1,166,285.75
If the quotient is a whole number, then 4 and 1,166,285.75 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 | 4,665,143 | |
| -1 | 4,665,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 67 | 203 | 343 | 469 | 1,421 | 1,943 | 2,401 | 3,283 | 9,947 | 13,601 | 22,981 | 69,629 | 95,207 | 160,867 | 666,449 | 4,665,143 |
| -1 | -7 | -29 | -49 | -67 | -203 | -343 | -469 | -1,421 | -1,943 | -2,401 | -3,283 | -9,947 | -13,601 | -22,981 | -69,629 | -95,207 | -160,867 | -666,449 | -4,665,143 |
