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 105,053,095, 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 | 105,053,095 | |
| -1 | -105,053,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,053,095.
Example:
1 x 105,053,095 = 105,053,095
and
-1 x -105,053,095 = 105,053,095
Notice both answers equal 105,053,095
With that explanation out of the way, let's continue. Next, we take the number 105,053,095 and divide it by 2:
105,053,095 ÷ 2 = 52,526,547.5
If the quotient is a whole number, then 2 and 52,526,547.5 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 | 105,053,095 | |
| -1 | -105,053,095 |
Now, we try dividing 105,053,095 by 3:
105,053,095 ÷ 3 = 35,017,698.3333
If the quotient is a whole number, then 3 and 35,017,698.3333 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 | 105,053,095 | |
| -1 | -105,053,095 |
Let's try dividing by 4:
105,053,095 ÷ 4 = 26,263,273.75
If the quotient is a whole number, then 4 and 26,263,273.75 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 | 105,053,095 | |
| -1 | 105,053,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 199 | 995 | 1,393 | 6,965 | 15,083 | 75,415 | 105,581 | 527,905 | 3,001,517 | 15,007,585 | 21,010,619 | 105,053,095 |
| -1 | -5 | -7 | -35 | -199 | -995 | -1,393 | -6,965 | -15,083 | -75,415 | -105,581 | -527,905 | -3,001,517 | -15,007,585 | -21,010,619 | -105,053,095 |
