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 64,634,719, 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 | 64,634,719 | |
| -1 | -64,634,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,634,719.
Example:
1 x 64,634,719 = 64,634,719
and
-1 x -64,634,719 = 64,634,719
Notice both answers equal 64,634,719
With that explanation out of the way, let's continue. Next, we take the number 64,634,719 and divide it by 2:
64,634,719 ÷ 2 = 32,317,359.5
If the quotient is a whole number, then 2 and 32,317,359.5 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 | 64,634,719 | |
| -1 | -64,634,719 |
Now, we try dividing 64,634,719 by 3:
64,634,719 ÷ 3 = 21,544,906.3333
If the quotient is a whole number, then 3 and 21,544,906.3333 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 | 64,634,719 | |
| -1 | -64,634,719 |
Let's try dividing by 4:
64,634,719 ÷ 4 = 16,158,679.75
If the quotient is a whole number, then 4 and 16,158,679.75 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 | 64,634,719 | |
| -1 | 64,634,719 |
If you did it right, you will end up with this table:
| 1 | 43 | 53 | 79 | 359 | 2,279 | 3,397 | 4,187 | 15,437 | 19,027 | 28,361 | 180,041 | 818,161 | 1,219,523 | 1,503,133 | 64,634,719 |
| -1 | -43 | -53 | -79 | -359 | -2,279 | -3,397 | -4,187 | -15,437 | -19,027 | -28,361 | -180,041 | -818,161 | -1,219,523 | -1,503,133 | -64,634,719 |
