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 45,384,451, 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 | 45,384,451 | |
| -1 | -45,384,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,384,451.
Example:
1 x 45,384,451 = 45,384,451
and
-1 x -45,384,451 = 45,384,451
Notice both answers equal 45,384,451
With that explanation out of the way, let's continue. Next, we take the number 45,384,451 and divide it by 2:
45,384,451 ÷ 2 = 22,692,225.5
If the quotient is a whole number, then 2 and 22,692,225.5 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 | 45,384,451 | |
| -1 | -45,384,451 |
Now, we try dividing 45,384,451 by 3:
45,384,451 ÷ 3 = 15,128,150.3333
If the quotient is a whole number, then 3 and 15,128,150.3333 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 | 45,384,451 | |
| -1 | -45,384,451 |
Let's try dividing by 4:
45,384,451 ÷ 4 = 11,346,112.75
If the quotient is a whole number, then 4 and 11,346,112.75 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 | 45,384,451 | |
| -1 | 45,384,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 101 | 161 | 707 | 2,323 | 2,791 | 16,261 | 19,537 | 64,193 | 281,891 | 449,351 | 1,973,237 | 6,483,493 | 45,384,451 |
| -1 | -7 | -23 | -101 | -161 | -707 | -2,323 | -2,791 | -16,261 | -19,537 | -64,193 | -281,891 | -449,351 | -1,973,237 | -6,483,493 | -45,384,451 |
