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 70,169,297, 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 | 70,169,297 | |
| -1 | -70,169,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,169,297.
Example:
1 x 70,169,297 = 70,169,297
and
-1 x -70,169,297 = 70,169,297
Notice both answers equal 70,169,297
With that explanation out of the way, let's continue. Next, we take the number 70,169,297 and divide it by 2:
70,169,297 ÷ 2 = 35,084,648.5
If the quotient is a whole number, then 2 and 35,084,648.5 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 | 70,169,297 | |
| -1 | -70,169,297 |
Now, we try dividing 70,169,297 by 3:
70,169,297 ÷ 3 = 23,389,765.6667
If the quotient is a whole number, then 3 and 23,389,765.6667 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 | 70,169,297 | |
| -1 | -70,169,297 |
Let's try dividing by 4:
70,169,297 ÷ 4 = 17,542,324.25
If the quotient is a whole number, then 4 and 17,542,324.25 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 | 70,169,297 | |
| -1 | 70,169,297 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 53 | 253 | 583 | 1,219 | 5,233 | 13,409 | 57,563 | 120,359 | 277,349 | 1,323,949 | 3,050,839 | 6,379,027 | 70,169,297 |
| -1 | -11 | -23 | -53 | -253 | -583 | -1,219 | -5,233 | -13,409 | -57,563 | -120,359 | -277,349 | -1,323,949 | -3,050,839 | -6,379,027 | -70,169,297 |
