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 43,116,415, 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 | 43,116,415 | |
| -1 | -43,116,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,116,415.
Example:
1 x 43,116,415 = 43,116,415
and
-1 x -43,116,415 = 43,116,415
Notice both answers equal 43,116,415
With that explanation out of the way, let's continue. Next, we take the number 43,116,415 and divide it by 2:
43,116,415 ÷ 2 = 21,558,207.5
If the quotient is a whole number, then 2 and 21,558,207.5 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 | 43,116,415 | |
| -1 | -43,116,415 |
Now, we try dividing 43,116,415 by 3:
43,116,415 ÷ 3 = 14,372,138.3333
If the quotient is a whole number, then 3 and 14,372,138.3333 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 | 43,116,415 | |
| -1 | -43,116,415 |
Let's try dividing by 4:
43,116,415 ÷ 4 = 10,779,103.75
If the quotient is a whole number, then 4 and 10,779,103.75 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 | 43,116,415 | |
| -1 | 43,116,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 293 | 1,465 | 1,549 | 5,567 | 7,745 | 27,835 | 29,431 | 147,155 | 453,857 | 2,269,285 | 8,623,283 | 43,116,415 |
| -1 | -5 | -19 | -95 | -293 | -1,465 | -1,549 | -5,567 | -7,745 | -27,835 | -29,431 | -147,155 | -453,857 | -2,269,285 | -8,623,283 | -43,116,415 |
