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 43,264,615, 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 | 43,264,615 | |
| -1 | -43,264,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,264,615.
Example:
1 x 43,264,615 = 43,264,615
and
-1 x -43,264,615 = 43,264,615
Notice both answers equal 43,264,615
With that explanation out of the way, let's continue. Next, we take the number 43,264,615 and divide it by 2:
43,264,615 ÷ 2 = 21,632,307.5
If the quotient is a whole number, then 2 and 21,632,307.5 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 | 43,264,615 | |
| -1 | -43,264,615 |
Now, we try dividing 43,264,615 by 3:
43,264,615 ÷ 3 = 14,421,538.3333
If the quotient is a whole number, then 3 and 14,421,538.3333 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 | 43,264,615 | |
| -1 | -43,264,615 |
Let's try dividing by 4:
43,264,615 ÷ 4 = 10,816,153.75
If the quotient is a whole number, then 4 and 10,816,153.75 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 | 43,264,615 | |
| -1 | 43,264,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 269 | 1,345 | 1,693 | 5,111 | 8,465 | 25,555 | 32,167 | 160,835 | 455,417 | 2,277,085 | 8,652,923 | 43,264,615 |
| -1 | -5 | -19 | -95 | -269 | -1,345 | -1,693 | -5,111 | -8,465 | -25,555 | -32,167 | -160,835 | -455,417 | -2,277,085 | -8,652,923 | -43,264,615 |
