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 24,142,465, 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 | 24,142,465 | |
| -1 | -24,142,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,142,465.
Example:
1 x 24,142,465 = 24,142,465
and
-1 x -24,142,465 = 24,142,465
Notice both answers equal 24,142,465
With that explanation out of the way, let's continue. Next, we take the number 24,142,465 and divide it by 2:
24,142,465 ÷ 2 = 12,071,232.5
If the quotient is a whole number, then 2 and 12,071,232.5 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 | 24,142,465 | |
| -1 | -24,142,465 |
Now, we try dividing 24,142,465 by 3:
24,142,465 ÷ 3 = 8,047,488.3333
If the quotient is a whole number, then 3 and 8,047,488.3333 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 | 24,142,465 | |
| -1 | -24,142,465 |
Let's try dividing by 4:
24,142,465 ÷ 4 = 6,035,616.25
If the quotient is a whole number, then 4 and 6,035,616.25 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 | 24,142,465 | |
| -1 | 24,142,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 431 | 659 | 2,155 | 3,295 | 7,327 | 11,203 | 36,635 | 56,015 | 284,029 | 1,420,145 | 4,828,493 | 24,142,465 |
| -1 | -5 | -17 | -85 | -431 | -659 | -2,155 | -3,295 | -7,327 | -11,203 | -36,635 | -56,015 | -284,029 | -1,420,145 | -4,828,493 | -24,142,465 |
