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 24,534,643, 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 | 24,534,643 | |
| -1 | -24,534,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,534,643.
Example:
1 x 24,534,643 = 24,534,643
and
-1 x -24,534,643 = 24,534,643
Notice both answers equal 24,534,643
With that explanation out of the way, let's continue. Next, we take the number 24,534,643 and divide it by 2:
24,534,643 ÷ 2 = 12,267,321.5
If the quotient is a whole number, then 2 and 12,267,321.5 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 | 24,534,643 | |
| -1 | -24,534,643 |
Now, we try dividing 24,534,643 by 3:
24,534,643 ÷ 3 = 8,178,214.3333
If the quotient is a whole number, then 3 and 8,178,214.3333 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 | 24,534,643 | |
| -1 | -24,534,643 |
Let's try dividing by 4:
24,534,643 ÷ 4 = 6,133,660.75
If the quotient is a whole number, then 4 and 6,133,660.75 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 | 24,534,643 | |
| -1 | 24,534,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 73 | 133 | 361 | 511 | 931 | 1,387 | 2,527 | 3,577 | 6,859 | 9,709 | 17,689 | 26,353 | 48,013 | 67,963 | 184,471 | 336,091 | 500,707 | 1,291,297 | 3,504,949 | 24,534,643 |
| -1 | -7 | -19 | -49 | -73 | -133 | -361 | -511 | -931 | -1,387 | -2,527 | -3,577 | -6,859 | -9,709 | -17,689 | -26,353 | -48,013 | -67,963 | -184,471 | -336,091 | -500,707 | -1,291,297 | -3,504,949 | -24,534,643 |
