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 4,155,151, 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 | 4,155,151 | |
| -1 | -4,155,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,155,151.
Example:
1 x 4,155,151 = 4,155,151
and
-1 x -4,155,151 = 4,155,151
Notice both answers equal 4,155,151
With that explanation out of the way, let's continue. Next, we take the number 4,155,151 and divide it by 2:
4,155,151 ÷ 2 = 2,077,575.5
If the quotient is a whole number, then 2 and 2,077,575.5 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 | 4,155,151 | |
| -1 | -4,155,151 |
Now, we try dividing 4,155,151 by 3:
4,155,151 ÷ 3 = 1,385,050.3333
If the quotient is a whole number, then 3 and 1,385,050.3333 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 | 4,155,151 | |
| -1 | -4,155,151 |
Let's try dividing by 4:
4,155,151 ÷ 4 = 1,038,787.75
If the quotient is a whole number, then 4 and 1,038,787.75 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 | 4,155,151 | |
| -1 | 4,155,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 593 | 637 | 1,001 | 4,151 | 6,523 | 7,007 | 7,709 | 29,057 | 45,661 | 53,963 | 84,799 | 319,627 | 377,741 | 593,593 | 4,155,151 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -593 | -637 | -1,001 | -4,151 | -6,523 | -7,007 | -7,709 | -29,057 | -45,661 | -53,963 | -84,799 | -319,627 | -377,741 | -593,593 | -4,155,151 |
