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 701,642,875, 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 | 701,642,875 | |
| -1 | -701,642,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 701,642,875.
Example:
1 x 701,642,875 = 701,642,875
and
-1 x -701,642,875 = 701,642,875
Notice both answers equal 701,642,875
With that explanation out of the way, let's continue. Next, we take the number 701,642,875 and divide it by 2:
701,642,875 ÷ 2 = 350,821,437.5
If the quotient is a whole number, then 2 and 350,821,437.5 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 | 701,642,875 | |
| -1 | -701,642,875 |
Now, we try dividing 701,642,875 by 3:
701,642,875 ÷ 3 = 233,880,958.3333
If the quotient is a whole number, then 3 and 233,880,958.3333 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 | 701,642,875 | |
| -1 | -701,642,875 |
Let's try dividing by 4:
701,642,875 ÷ 4 = 175,410,718.75
If the quotient is a whole number, then 4 and 175,410,718.75 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 | 701,642,875 | |
| -1 | 701,642,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 2,089 | 2,687 | 10,445 | 13,435 | 52,225 | 67,175 | 261,125 | 335,875 | 5,613,143 | 28,065,715 | 140,328,575 | 701,642,875 |
| -1 | -5 | -25 | -125 | -2,089 | -2,687 | -10,445 | -13,435 | -52,225 | -67,175 | -261,125 | -335,875 | -5,613,143 | -28,065,715 | -140,328,575 | -701,642,875 |
