Question

factors of 30 50 9 24 18 42 14 2

Answer 1

Answer:

A factor, also called a divisor, is any number that divides evenly into another number. In other words, factors are the numbers we can multiply together to get a certain product:

explanation of term factor

You can also notice that dividing the product by its factor leaves no remainder.

Definition of the factor differs: some definitions claim that factor can be negative as well as positive, but in other cases, the term is restricted to positive factors only. For example, the factors of 8 are 1, 2, 4 and 8. But, from the other hand, if you multiply -2 times -4, you'll also obtain 8, therefore -2 and -4 are factors of 8 according to the first definition.

Technically, you can have negative factors, although it's not so popular to use them. For practical purposes, our factor calculator provides only positive factors. If you need negative ones for some reason, just add the minus in front of every obtained value:

Factors of 8 are: 1, 2, 4, 8

plus -1, -2, -4, -8 as well.

Divisibility rules

There are many rules of divisibility that greatly assist one in finding factors by hand. The most often used ones are:

2: Any even number is divisible by 2.

3: A number is divisible by 3 if the sum of the digits in the number is divisible by 3.

4: A number is divisible by 4 if the last two digits form a number that is divisible by 4.

5: Any number ending in 5 or 0 is divisible by 5.

6: A number is divisible by 6 if it is divisible by 2 and 3.

7: The divisibility rule of 7 also exists, but it's a bit more complicated. Find a short paragraph below.

8: If the last three digits form a number that is divisible by 8, then the entire number is divisible by 8.

9: If the sum of the digits is divisible by 9, the entire number is divisible by 9.

10: Any number ending in 0 is divisible by 10.

There are many aspects of mathematics where it's important to be able to find the factors. The factor calculator is helpful in finding the greatest common factor, least common multiple and prime factorization.
