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 61,463,311, 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 | 61,463,311 | |
| -1 | -61,463,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,463,311.
Example:
1 x 61,463,311 = 61,463,311
and
-1 x -61,463,311 = 61,463,311
Notice both answers equal 61,463,311
With that explanation out of the way, let's continue. Next, we take the number 61,463,311 and divide it by 2:
61,463,311 ÷ 2 = 30,731,655.5
If the quotient is a whole number, then 2 and 30,731,655.5 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 | 61,463,311 | |
| -1 | -61,463,311 |
Now, we try dividing 61,463,311 by 3:
61,463,311 ÷ 3 = 20,487,770.3333
If the quotient is a whole number, then 3 and 20,487,770.3333 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 | 61,463,311 | |
| -1 | -61,463,311 |
Let's try dividing by 4:
61,463,311 ÷ 4 = 15,365,827.75
If the quotient is a whole number, then 4 and 15,365,827.75 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 | 61,463,311 | |
| -1 | 61,463,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 89 | 91 | 623 | 1,157 | 7,589 | 8,099 | 53,123 | 98,657 | 675,421 | 690,599 | 4,727,947 | 8,780,473 | 61,463,311 |
| -1 | -7 | -13 | -89 | -91 | -623 | -1,157 | -7,589 | -8,099 | -53,123 | -98,657 | -675,421 | -690,599 | -4,727,947 | -8,780,473 | -61,463,311 |
