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 70,848,155, 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 | 70,848,155 | |
| -1 | -70,848,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,848,155.
Example:
1 x 70,848,155 = 70,848,155
and
-1 x -70,848,155 = 70,848,155
Notice both answers equal 70,848,155
With that explanation out of the way, let's continue. Next, we take the number 70,848,155 and divide it by 2:
70,848,155 ÷ 2 = 35,424,077.5
If the quotient is a whole number, then 2 and 35,424,077.5 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 | 70,848,155 | |
| -1 | -70,848,155 |
Now, we try dividing 70,848,155 by 3:
70,848,155 ÷ 3 = 23,616,051.6667
If the quotient is a whole number, then 3 and 23,616,051.6667 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 | 70,848,155 | |
| -1 | -70,848,155 |
Let's try dividing by 4:
70,848,155 ÷ 4 = 17,712,038.75
If the quotient is a whole number, then 4 and 17,712,038.75 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 | 70,848,155 | |
| -1 | 70,848,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 54,709 | 273,545 | 382,963 | 1,914,815 | 2,024,233 | 10,121,165 | 14,169,631 | 70,848,155 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -54,709 | -273,545 | -382,963 | -1,914,815 | -2,024,233 | -10,121,165 | -14,169,631 | -70,848,155 |
