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 7,152,475, 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 | 7,152,475 | |
| -1 | -7,152,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,152,475.
Example:
1 x 7,152,475 = 7,152,475
and
-1 x -7,152,475 = 7,152,475
Notice both answers equal 7,152,475
With that explanation out of the way, let's continue. Next, we take the number 7,152,475 and divide it by 2:
7,152,475 ÷ 2 = 3,576,237.5
If the quotient is a whole number, then 2 and 3,576,237.5 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 | 7,152,475 | |
| -1 | -7,152,475 |
Now, we try dividing 7,152,475 by 3:
7,152,475 ÷ 3 = 2,384,158.3333
If the quotient is a whole number, then 3 and 2,384,158.3333 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 | 7,152,475 | |
| -1 | -7,152,475 |
Let's try dividing by 4:
7,152,475 ÷ 4 = 1,788,118.75
If the quotient is a whole number, then 4 and 1,788,118.75 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 | 7,152,475 | |
| -1 | 7,152,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 275 | 341 | 775 | 839 | 1,705 | 4,195 | 8,525 | 9,229 | 20,975 | 26,009 | 46,145 | 130,045 | 230,725 | 286,099 | 650,225 | 1,430,495 | 7,152,475 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -275 | -341 | -775 | -839 | -1,705 | -4,195 | -8,525 | -9,229 | -20,975 | -26,009 | -46,145 | -130,045 | -230,725 | -286,099 | -650,225 | -1,430,495 | -7,152,475 |
