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 45,046,651, 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 | 45,046,651 | |
| -1 | -45,046,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,046,651.
Example:
1 x 45,046,651 = 45,046,651
and
-1 x -45,046,651 = 45,046,651
Notice both answers equal 45,046,651
With that explanation out of the way, let's continue. Next, we take the number 45,046,651 and divide it by 2:
45,046,651 ÷ 2 = 22,523,325.5
If the quotient is a whole number, then 2 and 22,523,325.5 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 | 45,046,651 | |
| -1 | -45,046,651 |
Now, we try dividing 45,046,651 by 3:
45,046,651 ÷ 3 = 15,015,550.3333
If the quotient is a whole number, then 3 and 15,015,550.3333 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 | 45,046,651 | |
| -1 | -45,046,651 |
Let's try dividing by 4:
45,046,651 ÷ 4 = 11,261,662.75
If the quotient is a whole number, then 4 and 11,261,662.75 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 | 45,046,651 | |
| -1 | 45,046,651 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 317 | 643 | 4,121 | 5,389 | 8,359 | 10,931 | 70,057 | 142,103 | 203,831 | 2,649,803 | 3,465,127 | 45,046,651 |
| -1 | -13 | -17 | -221 | -317 | -643 | -4,121 | -5,389 | -8,359 | -10,931 | -70,057 | -142,103 | -203,831 | -2,649,803 | -3,465,127 | -45,046,651 |
