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 43,234,615, 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 | 43,234,615 | |
| -1 | -43,234,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,234,615.
Example:
1 x 43,234,615 = 43,234,615
and
-1 x -43,234,615 = 43,234,615
Notice both answers equal 43,234,615
With that explanation out of the way, let's continue. Next, we take the number 43,234,615 and divide it by 2:
43,234,615 ÷ 2 = 21,617,307.5
If the quotient is a whole number, then 2 and 21,617,307.5 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 | 43,234,615 | |
| -1 | -43,234,615 |
Now, we try dividing 43,234,615 by 3:
43,234,615 ÷ 3 = 14,411,538.3333
If the quotient is a whole number, then 3 and 14,411,538.3333 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 | 43,234,615 | |
| -1 | -43,234,615 |
Let's try dividing by 4:
43,234,615 ÷ 4 = 10,808,653.75
If the quotient is a whole number, then 4 and 10,808,653.75 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 | 43,234,615 | |
| -1 | 43,234,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 73 | 155 | 365 | 2,263 | 3,821 | 11,315 | 19,105 | 118,451 | 278,933 | 592,255 | 1,394,665 | 8,646,923 | 43,234,615 |
| -1 | -5 | -31 | -73 | -155 | -365 | -2,263 | -3,821 | -11,315 | -19,105 | -118,451 | -278,933 | -592,255 | -1,394,665 | -8,646,923 | -43,234,615 |
