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 70,115,227, 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 | 70,115,227 | |
| -1 | -70,115,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,115,227.
Example:
1 x 70,115,227 = 70,115,227
and
-1 x -70,115,227 = 70,115,227
Notice both answers equal 70,115,227
With that explanation out of the way, let's continue. Next, we take the number 70,115,227 and divide it by 2:
70,115,227 ÷ 2 = 35,057,613.5
If the quotient is a whole number, then 2 and 35,057,613.5 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 | 70,115,227 | |
| -1 | -70,115,227 |
Now, we try dividing 70,115,227 by 3:
70,115,227 ÷ 3 = 23,371,742.3333
If the quotient is a whole number, then 3 and 23,371,742.3333 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 | 70,115,227 | |
| -1 | -70,115,227 |
Let's try dividing by 4:
70,115,227 ÷ 4 = 17,528,806.75
If the quotient is a whole number, then 4 and 17,528,806.75 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 | 70,115,227 | |
| -1 | 70,115,227 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 637 | 1,183 | 8,281 | 8,467 | 59,269 | 110,071 | 414,883 | 770,497 | 1,430,923 | 5,393,479 | 10,016,461 | 70,115,227 |
| -1 | -7 | -13 | -49 | -91 | -169 | -637 | -1,183 | -8,281 | -8,467 | -59,269 | -110,071 | -414,883 | -770,497 | -1,430,923 | -5,393,479 | -10,016,461 | -70,115,227 |
