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 70,773,415, 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 | 70,773,415 | |
| -1 | -70,773,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,773,415.
Example:
1 x 70,773,415 = 70,773,415
and
-1 x -70,773,415 = 70,773,415
Notice both answers equal 70,773,415
With that explanation out of the way, let's continue. Next, we take the number 70,773,415 and divide it by 2:
70,773,415 ÷ 2 = 35,386,707.5
If the quotient is a whole number, then 2 and 35,386,707.5 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 | 70,773,415 | |
| -1 | -70,773,415 |
Now, we try dividing 70,773,415 by 3:
70,773,415 ÷ 3 = 23,591,138.3333
If the quotient is a whole number, then 3 and 23,591,138.3333 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 | 70,773,415 | |
| -1 | -70,773,415 |
Let's try dividing by 4:
70,773,415 ÷ 4 = 17,693,353.75
If the quotient is a whole number, then 4 and 17,693,353.75 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 | 70,773,415 | |
| -1 | 70,773,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 16,633 | 83,165 | 382,559 | 615,421 | 1,912,795 | 3,077,105 | 14,154,683 | 70,773,415 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -16,633 | -83,165 | -382,559 | -615,421 | -1,912,795 | -3,077,105 | -14,154,683 | -70,773,415 |
