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 61,738,285, 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 | 61,738,285 | |
| -1 | -61,738,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,738,285.
Example:
1 x 61,738,285 = 61,738,285
and
-1 x -61,738,285 = 61,738,285
Notice both answers equal 61,738,285
With that explanation out of the way, let's continue. Next, we take the number 61,738,285 and divide it by 2:
61,738,285 ÷ 2 = 30,869,142.5
If the quotient is a whole number, then 2 and 30,869,142.5 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 | 61,738,285 | |
| -1 | -61,738,285 |
Now, we try dividing 61,738,285 by 3:
61,738,285 ÷ 3 = 20,579,428.3333
If the quotient is a whole number, then 3 and 20,579,428.3333 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 | 61,738,285 | |
| -1 | -61,738,285 |
Let's try dividing by 4:
61,738,285 ÷ 4 = 15,434,571.25
If the quotient is a whole number, then 4 and 15,434,571.25 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 | 61,738,285 | |
| -1 | 61,738,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 35,999 | 179,995 | 251,993 | 1,259,965 | 1,763,951 | 8,819,755 | 12,347,657 | 61,738,285 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -35,999 | -179,995 | -251,993 | -1,259,965 | -1,763,951 | -8,819,755 | -12,347,657 | -61,738,285 |
