What are the uses of prime and composite numbers?

All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one


Is 16 a common multiple?

A common multiple is a multiple that two or more given numbers have in common. 16 is not a common multiple of 7 and 8. 16 is a common multiple of 4 and 8. So, it depends on the numbers for which you are trying to find a common multiple.


When a multiple is shared by two or more numbers that multiple is called?

A common multiple. If it is the lowest possible combination of those numbers, it is called the Least Common Multiple or LCM.

Is the LCM of a prime number and a composite number a multiple of the prime number?

If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).


How do you find the least common multiple of a monomial?

It's the same process as composite numbers. Factor them. Combine the factors, eliminating duplicates. If they have no common factors, the LCM is their product.


How do you get a common multiple?

The easiest way is to multiply the numbers together. The answer won't necessarily be the least common multiple, but it will be a common multiple. The easiest way to get a common multiple is to multiply the numbers together. The result will not necessarily be the least common multiple, but it will be a common multiple.
