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 42,056,203, 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 | 42,056,203 | |
| -1 | -42,056,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,056,203.
Example:
1 x 42,056,203 = 42,056,203
and
-1 x -42,056,203 = 42,056,203
Notice both answers equal 42,056,203
With that explanation out of the way, let's continue. Next, we take the number 42,056,203 and divide it by 2:
42,056,203 ÷ 2 = 21,028,101.5
If the quotient is a whole number, then 2 and 21,028,101.5 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 | 42,056,203 | |
| -1 | -42,056,203 |
Now, we try dividing 42,056,203 by 3:
42,056,203 ÷ 3 = 14,018,734.3333
If the quotient is a whole number, then 3 and 14,018,734.3333 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 | 42,056,203 | |
| -1 | -42,056,203 |
Let's try dividing by 4:
42,056,203 ÷ 4 = 10,514,050.75
If the quotient is a whole number, then 4 and 10,514,050.75 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 | 42,056,203 | |
| -1 | 42,056,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 79 | 413 | 553 | 1,289 | 4,661 | 9,023 | 32,627 | 76,051 | 101,831 | 532,357 | 712,817 | 6,008,029 | 42,056,203 |
| -1 | -7 | -59 | -79 | -413 | -553 | -1,289 | -4,661 | -9,023 | -32,627 | -76,051 | -101,831 | -532,357 | -712,817 | -6,008,029 | -42,056,203 |
