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 42,038,059, 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 | 42,038,059 | |
| -1 | -42,038,059 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,038,059.
Example:
1 x 42,038,059 = 42,038,059
and
-1 x -42,038,059 = 42,038,059
Notice both answers equal 42,038,059
With that explanation out of the way, let's continue. Next, we take the number 42,038,059 and divide it by 2:
42,038,059 ÷ 2 = 21,019,029.5
If the quotient is a whole number, then 2 and 21,019,029.5 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 | 42,038,059 | |
| -1 | -42,038,059 |
Now, we try dividing 42,038,059 by 3:
42,038,059 ÷ 3 = 14,012,686.3333
If the quotient is a whole number, then 3 and 14,012,686.3333 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 | 42,038,059 | |
| -1 | -42,038,059 |
Let's try dividing by 4:
42,038,059 ÷ 4 = 10,509,514.75
If the quotient is a whole number, then 4 and 10,509,514.75 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 | 42,038,059 | |
| -1 | 42,038,059 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 457 | 773 | 3,199 | 5,411 | 7,769 | 13,141 | 54,383 | 91,987 | 353,261 | 2,472,827 | 6,005,437 | 42,038,059 |
| -1 | -7 | -17 | -119 | -457 | -773 | -3,199 | -5,411 | -7,769 | -13,141 | -54,383 | -91,987 | -353,261 | -2,472,827 | -6,005,437 | -42,038,059 |
