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 48,719,297, 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 | 48,719,297 | |
| -1 | -48,719,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,719,297.
Example:
1 x 48,719,297 = 48,719,297
and
-1 x -48,719,297 = 48,719,297
Notice both answers equal 48,719,297
With that explanation out of the way, let's continue. Next, we take the number 48,719,297 and divide it by 2:
48,719,297 ÷ 2 = 24,359,648.5
If the quotient is a whole number, then 2 and 24,359,648.5 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 | 48,719,297 | |
| -1 | -48,719,297 |
Now, we try dividing 48,719,297 by 3:
48,719,297 ÷ 3 = 16,239,765.6667
If the quotient is a whole number, then 3 and 16,239,765.6667 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 | 48,719,297 | |
| -1 | -48,719,297 |
Let's try dividing by 4:
48,719,297 ÷ 4 = 12,179,824.25
If the quotient is a whole number, then 4 and 12,179,824.25 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 | 48,719,297 | |
| -1 | 48,719,297 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 61 | 187 | 671 | 1,037 | 4,271 | 11,407 | 46,981 | 72,607 | 260,531 | 798,677 | 2,865,841 | 4,429,027 | 48,719,297 |
| -1 | -11 | -17 | -61 | -187 | -671 | -1,037 | -4,271 | -11,407 | -46,981 | -72,607 | -260,531 | -798,677 | -2,865,841 | -4,429,027 | -48,719,297 |
