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 48,460,643, 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 | 48,460,643 | |
| -1 | -48,460,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,460,643.
Example:
1 x 48,460,643 = 48,460,643
and
-1 x -48,460,643 = 48,460,643
Notice both answers equal 48,460,643
With that explanation out of the way, let's continue. Next, we take the number 48,460,643 and divide it by 2:
48,460,643 ÷ 2 = 24,230,321.5
If the quotient is a whole number, then 2 and 24,230,321.5 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 | 48,460,643 | |
| -1 | -48,460,643 |
Now, we try dividing 48,460,643 by 3:
48,460,643 ÷ 3 = 16,153,547.6667
If the quotient is a whole number, then 3 and 16,153,547.6667 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 | 48,460,643 | |
| -1 | -48,460,643 |
Let's try dividing by 4:
48,460,643 ÷ 4 = 12,115,160.75
If the quotient is a whole number, then 4 and 12,115,160.75 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 | 48,460,643 | |
| -1 | 48,460,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 263 | 1,841 | 2,393 | 2,893 | 16,751 | 20,251 | 26,323 | 184,261 | 629,359 | 4,405,513 | 6,922,949 | 48,460,643 |
| -1 | -7 | -11 | -77 | -263 | -1,841 | -2,393 | -2,893 | -16,751 | -20,251 | -26,323 | -184,261 | -629,359 | -4,405,513 | -6,922,949 | -48,460,643 |
