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 42,761,411, 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 | 42,761,411 | |
| -1 | -42,761,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,761,411.
Example:
1 x 42,761,411 = 42,761,411
and
-1 x -42,761,411 = 42,761,411
Notice both answers equal 42,761,411
With that explanation out of the way, let's continue. Next, we take the number 42,761,411 and divide it by 2:
42,761,411 ÷ 2 = 21,380,705.5
If the quotient is a whole number, then 2 and 21,380,705.5 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 | 42,761,411 | |
| -1 | -42,761,411 |
Now, we try dividing 42,761,411 by 3:
42,761,411 ÷ 3 = 14,253,803.6667
If the quotient is a whole number, then 3 and 14,253,803.6667 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 | 42,761,411 | |
| -1 | -42,761,411 |
Let's try dividing by 4:
42,761,411 ÷ 4 = 10,690,352.75
If the quotient is a whole number, then 4 and 10,690,352.75 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 | 42,761,411 | |
| -1 | 42,761,411 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 197 | 1,379 | 2,167 | 2,819 | 15,169 | 19,733 | 31,009 | 217,063 | 555,343 | 3,887,401 | 6,108,773 | 42,761,411 |
| -1 | -7 | -11 | -77 | -197 | -1,379 | -2,167 | -2,819 | -15,169 | -19,733 | -31,009 | -217,063 | -555,343 | -3,887,401 | -6,108,773 | -42,761,411 |
