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 46,500,391, 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 | 46,500,391 | |
| -1 | -46,500,391 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,500,391.
Example:
1 x 46,500,391 = 46,500,391
and
-1 x -46,500,391 = 46,500,391
Notice both answers equal 46,500,391
With that explanation out of the way, let's continue. Next, we take the number 46,500,391 and divide it by 2:
46,500,391 ÷ 2 = 23,250,195.5
If the quotient is a whole number, then 2 and 23,250,195.5 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 | 46,500,391 | |
| -1 | -46,500,391 |
Now, we try dividing 46,500,391 by 3:
46,500,391 ÷ 3 = 15,500,130.3333
If the quotient is a whole number, then 3 and 15,500,130.3333 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 | 46,500,391 | |
| -1 | -46,500,391 |
Let's try dividing by 4:
46,500,391 ÷ 4 = 11,625,097.75
If the quotient is a whole number, then 4 and 11,625,097.75 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 | 46,500,391 | |
| -1 | 46,500,391 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 211 | 1,477 | 1,657 | 4,009 | 11,599 | 28,063 | 31,483 | 220,381 | 349,627 | 2,447,389 | 6,642,913 | 46,500,391 |
| -1 | -7 | -19 | -133 | -211 | -1,477 | -1,657 | -4,009 | -11,599 | -28,063 | -31,483 | -220,381 | -349,627 | -2,447,389 | -6,642,913 | -46,500,391 |
