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 42,053,683, 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 | 42,053,683 | |
| -1 | -42,053,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,053,683.
Example:
1 x 42,053,683 = 42,053,683
and
-1 x -42,053,683 = 42,053,683
Notice both answers equal 42,053,683
With that explanation out of the way, let's continue. Next, we take the number 42,053,683 and divide it by 2:
42,053,683 ÷ 2 = 21,026,841.5
If the quotient is a whole number, then 2 and 21,026,841.5 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 | 42,053,683 | |
| -1 | -42,053,683 |
Now, we try dividing 42,053,683 by 3:
42,053,683 ÷ 3 = 14,017,894.3333
If the quotient is a whole number, then 3 and 14,017,894.3333 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 | 42,053,683 | |
| -1 | -42,053,683 |
Let's try dividing by 4:
42,053,683 ÷ 4 = 10,513,420.75
If the quotient is a whole number, then 4 and 10,513,420.75 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 | 42,053,683 | |
| -1 | 42,053,683 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 9,007 | 63,049 | 207,161 | 261,203 | 1,450,127 | 1,828,421 | 6,007,669 | 42,053,683 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -9,007 | -63,049 | -207,161 | -261,203 | -1,450,127 | -1,828,421 | -6,007,669 | -42,053,683 |
