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 43,042,315, 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 | 43,042,315 | |
| -1 | -43,042,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,042,315.
Example:
1 x 43,042,315 = 43,042,315
and
-1 x -43,042,315 = 43,042,315
Notice both answers equal 43,042,315
With that explanation out of the way, let's continue. Next, we take the number 43,042,315 and divide it by 2:
43,042,315 ÷ 2 = 21,521,157.5
If the quotient is a whole number, then 2 and 21,521,157.5 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 | 43,042,315 | |
| -1 | -43,042,315 |
Now, we try dividing 43,042,315 by 3:
43,042,315 ÷ 3 = 14,347,438.3333
If the quotient is a whole number, then 3 and 14,347,438.3333 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 | 43,042,315 | |
| -1 | -43,042,315 |
Let's try dividing by 4:
43,042,315 ÷ 4 = 10,760,578.75
If the quotient is a whole number, then 4 and 10,760,578.75 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 | 43,042,315 | |
| -1 | 43,042,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 19,699 | 98,495 | 374,281 | 453,077 | 1,871,405 | 2,265,385 | 8,608,463 | 43,042,315 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -19,699 | -98,495 | -374,281 | -453,077 | -1,871,405 | -2,265,385 | -8,608,463 | -43,042,315 |
