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 45,078,131, 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 | 45,078,131 | |
| -1 | -45,078,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,078,131.
Example:
1 x 45,078,131 = 45,078,131
and
-1 x -45,078,131 = 45,078,131
Notice both answers equal 45,078,131
With that explanation out of the way, let's continue. Next, we take the number 45,078,131 and divide it by 2:
45,078,131 ÷ 2 = 22,539,065.5
If the quotient is a whole number, then 2 and 22,539,065.5 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 | 45,078,131 | |
| -1 | -45,078,131 |
Now, we try dividing 45,078,131 by 3:
45,078,131 ÷ 3 = 15,026,043.6667
If the quotient is a whole number, then 3 and 15,026,043.6667 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 | 45,078,131 | |
| -1 | -45,078,131 |
Let's try dividing by 4:
45,078,131 ÷ 4 = 11,269,532.75
If the quotient is a whole number, then 4 and 11,269,532.75 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 | 45,078,131 | |
| -1 | 45,078,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 197 | 337 | 679 | 1,379 | 2,359 | 19,109 | 32,689 | 66,389 | 133,763 | 228,823 | 464,723 | 6,439,733 | 45,078,131 |
| -1 | -7 | -97 | -197 | -337 | -679 | -1,379 | -2,359 | -19,109 | -32,689 | -66,389 | -133,763 | -228,823 | -464,723 | -6,439,733 | -45,078,131 |
