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 371,472,763, 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 | 371,472,763 | |
| -1 | -371,472,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,472,763.
Example:
1 x 371,472,763 = 371,472,763
and
-1 x -371,472,763 = 371,472,763
Notice both answers equal 371,472,763
With that explanation out of the way, let's continue. Next, we take the number 371,472,763 and divide it by 2:
371,472,763 ÷ 2 = 185,736,381.5
If the quotient is a whole number, then 2 and 185,736,381.5 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 | 371,472,763 | |
| -1 | -371,472,763 |
Now, we try dividing 371,472,763 by 3:
371,472,763 ÷ 3 = 123,824,254.3333
If the quotient is a whole number, then 3 and 123,824,254.3333 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 | 371,472,763 | |
| -1 | -371,472,763 |
Let's try dividing by 4:
371,472,763 ÷ 4 = 92,868,190.75
If the quotient is a whole number, then 4 and 92,868,190.75 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 | 371,472,763 | |
| -1 | 371,472,763 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 307 | 653 | 1,853 | 5,219 | 11,101 | 33,463 | 71,177 | 200,471 | 568,871 | 1,210,009 | 3,408,007 | 21,851,339 | 371,472,763 |
| -1 | -17 | -109 | -307 | -653 | -1,853 | -5,219 | -11,101 | -33,463 | -71,177 | -200,471 | -568,871 | -1,210,009 | -3,408,007 | -21,851,339 | -371,472,763 |
