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 73,570,237, 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 | 73,570,237 | |
| -1 | -73,570,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,570,237.
Example:
1 x 73,570,237 = 73,570,237
and
-1 x -73,570,237 = 73,570,237
Notice both answers equal 73,570,237
With that explanation out of the way, let's continue. Next, we take the number 73,570,237 and divide it by 2:
73,570,237 ÷ 2 = 36,785,118.5
If the quotient is a whole number, then 2 and 36,785,118.5 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 | 73,570,237 | |
| -1 | -73,570,237 |
Now, we try dividing 73,570,237 by 3:
73,570,237 ÷ 3 = 24,523,412.3333
If the quotient is a whole number, then 3 and 24,523,412.3333 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 | 73,570,237 | |
| -1 | -73,570,237 |
Let's try dividing by 4:
73,570,237 ÷ 4 = 18,392,559.25
If the quotient is a whole number, then 4 and 18,392,559.25 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 | 73,570,237 | |
| -1 | 73,570,237 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 463 | 719 | 6,019 | 7,871 | 9,347 | 12,223 | 102,323 | 158,899 | 332,897 | 4,327,661 | 5,659,249 | 73,570,237 |
| -1 | -13 | -17 | -221 | -463 | -719 | -6,019 | -7,871 | -9,347 | -12,223 | -102,323 | -158,899 | -332,897 | -4,327,661 | -5,659,249 | -73,570,237 |
