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 70,620,613, 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 | 70,620,613 | |
| -1 | -70,620,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,620,613.
Example:
1 x 70,620,613 = 70,620,613
and
-1 x -70,620,613 = 70,620,613
Notice both answers equal 70,620,613
With that explanation out of the way, let's continue. Next, we take the number 70,620,613 and divide it by 2:
70,620,613 ÷ 2 = 35,310,306.5
If the quotient is a whole number, then 2 and 35,310,306.5 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 | 70,620,613 | |
| -1 | -70,620,613 |
Now, we try dividing 70,620,613 by 3:
70,620,613 ÷ 3 = 23,540,204.3333
If the quotient is a whole number, then 3 and 23,540,204.3333 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 | 70,620,613 | |
| -1 | -70,620,613 |
Let's try dividing by 4:
70,620,613 ÷ 4 = 17,655,153.25
If the quotient is a whole number, then 4 and 17,655,153.25 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 | 70,620,613 | |
| -1 | 70,620,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 67 | 343 | 439 | 469 | 2,401 | 3,073 | 3,283 | 21,511 | 22,981 | 29,413 | 150,577 | 160,867 | 205,891 | 1,054,039 | 1,441,237 | 10,088,659 | 70,620,613 |
| -1 | -7 | -49 | -67 | -343 | -439 | -469 | -2,401 | -3,073 | -3,283 | -21,511 | -22,981 | -29,413 | -150,577 | -160,867 | -205,891 | -1,054,039 | -1,441,237 | -10,088,659 | -70,620,613 |
