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 48,121,577, 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 | 48,121,577 | |
| -1 | -48,121,577 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,121,577.
Example:
1 x 48,121,577 = 48,121,577
and
-1 x -48,121,577 = 48,121,577
Notice both answers equal 48,121,577
With that explanation out of the way, let's continue. Next, we take the number 48,121,577 and divide it by 2:
48,121,577 ÷ 2 = 24,060,788.5
If the quotient is a whole number, then 2 and 24,060,788.5 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 | 48,121,577 | |
| -1 | -48,121,577 |
Now, we try dividing 48,121,577 by 3:
48,121,577 ÷ 3 = 16,040,525.6667
If the quotient is a whole number, then 3 and 16,040,525.6667 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 | 48,121,577 | |
| -1 | -48,121,577 |
Let's try dividing by 4:
48,121,577 ÷ 4 = 12,030,394.25
If the quotient is a whole number, then 4 and 12,030,394.25 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 | 48,121,577 | |
| -1 | 48,121,577 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 41 | 49 | 119 | 287 | 697 | 833 | 1,409 | 2,009 | 4,879 | 9,863 | 23,953 | 34,153 | 57,769 | 69,041 | 167,671 | 404,383 | 982,073 | 1,173,697 | 2,830,681 | 6,874,511 | 48,121,577 |
| -1 | -7 | -17 | -41 | -49 | -119 | -287 | -697 | -833 | -1,409 | -2,009 | -4,879 | -9,863 | -23,953 | -34,153 | -57,769 | -69,041 | -167,671 | -404,383 | -982,073 | -1,173,697 | -2,830,681 | -6,874,511 | -48,121,577 |
