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 64,743,107, 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 | 64,743,107 | |
| -1 | -64,743,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,743,107.
Example:
1 x 64,743,107 = 64,743,107
and
-1 x -64,743,107 = 64,743,107
Notice both answers equal 64,743,107
With that explanation out of the way, let's continue. Next, we take the number 64,743,107 and divide it by 2:
64,743,107 ÷ 2 = 32,371,553.5
If the quotient is a whole number, then 2 and 32,371,553.5 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 | 64,743,107 | |
| -1 | -64,743,107 |
Now, we try dividing 64,743,107 by 3:
64,743,107 ÷ 3 = 21,581,035.6667
If the quotient is a whole number, then 3 and 21,581,035.6667 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 | 64,743,107 | |
| -1 | -64,743,107 |
Let's try dividing by 4:
64,743,107 ÷ 4 = 16,185,776.75
If the quotient is a whole number, then 4 and 16,185,776.75 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 | 64,743,107 | |
| -1 | 64,743,107 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 79 | 121 | 143 | 521 | 869 | 1,027 | 1,573 | 5,731 | 6,773 | 9,559 | 11,297 | 41,159 | 63,041 | 74,503 | 124,267 | 452,749 | 535,067 | 819,533 | 4,980,239 | 5,885,737 | 64,743,107 |
| -1 | -11 | -13 | -79 | -121 | -143 | -521 | -869 | -1,027 | -1,573 | -5,731 | -6,773 | -9,559 | -11,297 | -41,159 | -63,041 | -74,503 | -124,267 | -452,749 | -535,067 | -819,533 | -4,980,239 | -5,885,737 | -64,743,107 |
