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 43,724,051, 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 | 43,724,051 | |
| -1 | -43,724,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,724,051.
Example:
1 x 43,724,051 = 43,724,051
and
-1 x -43,724,051 = 43,724,051
Notice both answers equal 43,724,051
With that explanation out of the way, let's continue. Next, we take the number 43,724,051 and divide it by 2:
43,724,051 ÷ 2 = 21,862,025.5
If the quotient is a whole number, then 2 and 21,862,025.5 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 | 43,724,051 | |
| -1 | -43,724,051 |
Now, we try dividing 43,724,051 by 3:
43,724,051 ÷ 3 = 14,574,683.6667
If the quotient is a whole number, then 3 and 14,574,683.6667 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 | 43,724,051 | |
| -1 | -43,724,051 |
Let's try dividing by 4:
43,724,051 ÷ 4 = 10,931,012.75
If the quotient is a whole number, then 4 and 10,931,012.75 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 | 43,724,051 | |
| -1 | 43,724,051 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 79 | 119 | 553 | 1,343 | 4,651 | 9,401 | 32,557 | 79,067 | 367,429 | 553,469 | 2,572,003 | 6,246,293 | 43,724,051 |
| -1 | -7 | -17 | -79 | -119 | -553 | -1,343 | -4,651 | -9,401 | -32,557 | -79,067 | -367,429 | -553,469 | -2,572,003 | -6,246,293 | -43,724,051 |
