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 276,417,473, 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 | 276,417,473 | |
| -1 | -276,417,473 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,417,473.
Example:
1 x 276,417,473 = 276,417,473
and
-1 x -276,417,473 = 276,417,473
Notice both answers equal 276,417,473
With that explanation out of the way, let's continue. Next, we take the number 276,417,473 and divide it by 2:
276,417,473 ÷ 2 = 138,208,736.5
If the quotient is a whole number, then 2 and 138,208,736.5 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 | 276,417,473 | |
| -1 | -276,417,473 |
Now, we try dividing 276,417,473 by 3:
276,417,473 ÷ 3 = 92,139,157.6667
If the quotient is a whole number, then 3 and 92,139,157.6667 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 | 276,417,473 | |
| -1 | -276,417,473 |
Let's try dividing by 4:
276,417,473 ÷ 4 = 69,104,368.25
If the quotient is a whole number, then 4 and 69,104,368.25 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 | 276,417,473 | |
| -1 | 276,417,473 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 83 | 667 | 1,909 | 2,407 | 4,993 | 55,361 | 114,839 | 144,797 | 414,419 | 3,330,331 | 9,531,637 | 12,018,151 | 276,417,473 |
| -1 | -23 | -29 | -83 | -667 | -1,909 | -2,407 | -4,993 | -55,361 | -114,839 | -144,797 | -414,419 | -3,330,331 | -9,531,637 | -12,018,151 | -276,417,473 |
