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 46,451,821, 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 | 46,451,821 | |
| -1 | -46,451,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,451,821.
Example:
1 x 46,451,821 = 46,451,821
and
-1 x -46,451,821 = 46,451,821
Notice both answers equal 46,451,821
With that explanation out of the way, let's continue. Next, we take the number 46,451,821 and divide it by 2:
46,451,821 ÷ 2 = 23,225,910.5
If the quotient is a whole number, then 2 and 23,225,910.5 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 | 46,451,821 | |
| -1 | -46,451,821 |
Now, we try dividing 46,451,821 by 3:
46,451,821 ÷ 3 = 15,483,940.3333
If the quotient is a whole number, then 3 and 15,483,940.3333 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 | 46,451,821 | |
| -1 | -46,451,821 |
Let's try dividing by 4:
46,451,821 ÷ 4 = 11,612,955.25
If the quotient is a whole number, then 4 and 11,612,955.25 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 | 46,451,821 | |
| -1 | 46,451,821 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 71 | 767 | 853 | 923 | 4,189 | 11,089 | 50,327 | 54,457 | 60,563 | 654,251 | 787,319 | 3,573,217 | 46,451,821 |
| -1 | -13 | -59 | -71 | -767 | -853 | -923 | -4,189 | -11,089 | -50,327 | -54,457 | -60,563 | -654,251 | -787,319 | -3,573,217 | -46,451,821 |
