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 61,058,039, 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 | 61,058,039 | |
| -1 | -61,058,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,058,039.
Example:
1 x 61,058,039 = 61,058,039
and
-1 x -61,058,039 = 61,058,039
Notice both answers equal 61,058,039
With that explanation out of the way, let's continue. Next, we take the number 61,058,039 and divide it by 2:
61,058,039 ÷ 2 = 30,529,019.5
If the quotient is a whole number, then 2 and 30,529,019.5 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 | 61,058,039 | |
| -1 | -61,058,039 |
Now, we try dividing 61,058,039 by 3:
61,058,039 ÷ 3 = 20,352,679.6667
If the quotient is a whole number, then 3 and 20,352,679.6667 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 | 61,058,039 | |
| -1 | -61,058,039 |
Let's try dividing by 4:
61,058,039 ÷ 4 = 15,264,509.75
If the quotient is a whole number, then 4 and 15,264,509.75 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 | 61,058,039 | |
| -1 | 61,058,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 167 | 1,169 | 2,749 | 3,173 | 19,243 | 22,211 | 52,231 | 365,617 | 459,083 | 3,213,581 | 8,722,577 | 61,058,039 |
| -1 | -7 | -19 | -133 | -167 | -1,169 | -2,749 | -3,173 | -19,243 | -22,211 | -52,231 | -365,617 | -459,083 | -3,213,581 | -8,722,577 | -61,058,039 |
