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 64,532,699, 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 | 64,532,699 | |
| -1 | -64,532,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,532,699.
Example:
1 x 64,532,699 = 64,532,699
and
-1 x -64,532,699 = 64,532,699
Notice both answers equal 64,532,699
With that explanation out of the way, let's continue. Next, we take the number 64,532,699 and divide it by 2:
64,532,699 ÷ 2 = 32,266,349.5
If the quotient is a whole number, then 2 and 32,266,349.5 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 | 64,532,699 | |
| -1 | -64,532,699 |
Now, we try dividing 64,532,699 by 3:
64,532,699 ÷ 3 = 21,510,899.6667
If the quotient is a whole number, then 3 and 21,510,899.6667 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 | 64,532,699 | |
| -1 | -64,532,699 |
Let's try dividing by 4:
64,532,699 ÷ 4 = 16,133,174.75
If the quotient is a whole number, then 4 and 16,133,174.75 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 | 64,532,699 | |
| -1 | 64,532,699 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 22,651 | 158,557 | 249,161 | 838,087 | 1,744,127 | 5,866,609 | 9,218,957 | 64,532,699 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -22,651 | -158,557 | -249,161 | -838,087 | -1,744,127 | -5,866,609 | -9,218,957 | -64,532,699 |
