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 61,161,053, 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 | 61,161,053 | |
| -1 | -61,161,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,161,053.
Example:
1 x 61,161,053 = 61,161,053
and
-1 x -61,161,053 = 61,161,053
Notice both answers equal 61,161,053
With that explanation out of the way, let's continue. Next, we take the number 61,161,053 and divide it by 2:
61,161,053 ÷ 2 = 30,580,526.5
If the quotient is a whole number, then 2 and 30,580,526.5 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 | 61,161,053 | |
| -1 | -61,161,053 |
Now, we try dividing 61,161,053 by 3:
61,161,053 ÷ 3 = 20,387,017.6667
If the quotient is a whole number, then 3 and 20,387,017.6667 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 | 61,161,053 | |
| -1 | -61,161,053 |
Let's try dividing by 4:
61,161,053 ÷ 4 = 15,290,263.25
If the quotient is a whole number, then 4 and 15,290,263.25 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 | 61,161,053 | |
| -1 | 61,161,053 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 47 | 697 | 799 | 1,867 | 1,927 | 31,739 | 32,759 | 76,547 | 87,749 | 1,301,299 | 1,491,733 | 3,597,709 | 61,161,053 |
| -1 | -17 | -41 | -47 | -697 | -799 | -1,867 | -1,927 | -31,739 | -32,759 | -76,547 | -87,749 | -1,301,299 | -1,491,733 | -3,597,709 | -61,161,053 |
