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 64,650,179, 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 | 64,650,179 | |
| -1 | -64,650,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,650,179.
Example:
1 x 64,650,179 = 64,650,179
and
-1 x -64,650,179 = 64,650,179
Notice both answers equal 64,650,179
With that explanation out of the way, let's continue. Next, we take the number 64,650,179 and divide it by 2:
64,650,179 ÷ 2 = 32,325,089.5
If the quotient is a whole number, then 2 and 32,325,089.5 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 | 64,650,179 | |
| -1 | -64,650,179 |
Now, we try dividing 64,650,179 by 3:
64,650,179 ÷ 3 = 21,550,059.6667
If the quotient is a whole number, then 3 and 21,550,059.6667 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 | 64,650,179 | |
| -1 | -64,650,179 |
Let's try dividing by 4:
64,650,179 ÷ 4 = 16,162,544.75
If the quotient is a whole number, then 4 and 16,162,544.75 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 | 64,650,179 | |
| -1 | 64,650,179 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 121 | 209 | 461 | 671 | 1,159 | 2,299 | 5,071 | 7,381 | 8,759 | 12,749 | 28,121 | 55,781 | 96,349 | 140,239 | 309,331 | 534,299 | 1,059,839 | 3,402,641 | 5,877,289 | 64,650,179 |
| -1 | -11 | -19 | -61 | -121 | -209 | -461 | -671 | -1,159 | -2,299 | -5,071 | -7,381 | -8,759 | -12,749 | -28,121 | -55,781 | -96,349 | -140,239 | -309,331 | -534,299 | -1,059,839 | -3,402,641 | -5,877,289 | -64,650,179 |
