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 100,645,283, 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 | 100,645,283 | |
| -1 | -100,645,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,645,283.
Example:
1 x 100,645,283 = 100,645,283
and
-1 x -100,645,283 = 100,645,283
Notice both answers equal 100,645,283
With that explanation out of the way, let's continue. Next, we take the number 100,645,283 and divide it by 2:
100,645,283 ÷ 2 = 50,322,641.5
If the quotient is a whole number, then 2 and 50,322,641.5 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 | 100,645,283 | |
| -1 | -100,645,283 |
Now, we try dividing 100,645,283 by 3:
100,645,283 ÷ 3 = 33,548,427.6667
If the quotient is a whole number, then 3 and 33,548,427.6667 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 | 100,645,283 | |
| -1 | -100,645,283 |
Let's try dividing by 4:
100,645,283 ÷ 4 = 25,161,320.75
If the quotient is a whole number, then 4 and 25,161,320.75 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 | 100,645,283 | |
| -1 | 100,645,283 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 47 | 1,189 | 1,363 | 1,801 | 1,927 | 52,229 | 55,883 | 73,841 | 84,647 | 2,141,389 | 2,454,763 | 3,470,527 | 100,645,283 |
| -1 | -29 | -41 | -47 | -1,189 | -1,363 | -1,801 | -1,927 | -52,229 | -55,883 | -73,841 | -84,647 | -2,141,389 | -2,454,763 | -3,470,527 | -100,645,283 |
