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 70,736,927, 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 | 70,736,927 | |
| -1 | -70,736,927 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,736,927.
Example:
1 x 70,736,927 = 70,736,927
and
-1 x -70,736,927 = 70,736,927
Notice both answers equal 70,736,927
With that explanation out of the way, let's continue. Next, we take the number 70,736,927 and divide it by 2:
70,736,927 ÷ 2 = 35,368,463.5
If the quotient is a whole number, then 2 and 35,368,463.5 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 | 70,736,927 | |
| -1 | -70,736,927 |
Now, we try dividing 70,736,927 by 3:
70,736,927 ÷ 3 = 23,578,975.6667
If the quotient is a whole number, then 3 and 23,578,975.6667 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 | 70,736,927 | |
| -1 | -70,736,927 |
Let's try dividing by 4:
70,736,927 ÷ 4 = 17,684,231.75
If the quotient is a whole number, then 4 and 17,684,231.75 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 | 70,736,927 | |
| -1 | 70,736,927 |
If you did it right, you will end up with this table:
| 1 | 47 | 53 | 73 | 389 | 2,491 | 3,431 | 3,869 | 18,283 | 20,617 | 28,397 | 181,843 | 968,999 | 1,334,659 | 1,505,041 | 70,736,927 |
| -1 | -47 | -53 | -73 | -389 | -2,491 | -3,431 | -3,869 | -18,283 | -20,617 | -28,397 | -181,843 | -968,999 | -1,334,659 | -1,505,041 | -70,736,927 |
