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 70,227,545, 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 | 70,227,545 | |
| -1 | -70,227,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,227,545.
Example:
1 x 70,227,545 = 70,227,545
and
-1 x -70,227,545 = 70,227,545
Notice both answers equal 70,227,545
With that explanation out of the way, let's continue. Next, we take the number 70,227,545 and divide it by 2:
70,227,545 ÷ 2 = 35,113,772.5
If the quotient is a whole number, then 2 and 35,113,772.5 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 | 70,227,545 | |
| -1 | -70,227,545 |
Now, we try dividing 70,227,545 by 3:
70,227,545 ÷ 3 = 23,409,181.6667
If the quotient is a whole number, then 3 and 23,409,181.6667 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 | 70,227,545 | |
| -1 | -70,227,545 |
Let's try dividing by 4:
70,227,545 ÷ 4 = 17,556,886.25
If the quotient is a whole number, then 4 and 17,556,886.25 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 | 70,227,545 | |
| -1 | 70,227,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 197 | 415 | 859 | 985 | 4,295 | 16,351 | 71,297 | 81,755 | 169,223 | 356,485 | 846,115 | 14,045,509 | 70,227,545 |
| -1 | -5 | -83 | -197 | -415 | -859 | -985 | -4,295 | -16,351 | -71,297 | -81,755 | -169,223 | -356,485 | -846,115 | -14,045,509 | -70,227,545 |
