Well yes, but it's kind of a meaningless distinction. All numbers are very close to a multiple of 3. Any non-zero number you can name is at most two away.

### What is the greatest common multiple of two prime numbers?

The greatest common multiple is an infinite amount and not very practical for problem solving. The least common multiple of two prime numbers is their product.

### Can 2 consecutive numbers in prime factorization be prime?

The only one pair of consecutive prime numbers possible are 2 and 3. After these very two numbers, every even number is a multiple of two. Furthermore, after 10, every number ending if five is a multiple of five. So, then no two prime numbers can be consecutive anymore. The span between prime numbers then only get wider and wider as the numbers continue to count upwards.

### Does the number your using count as the least common multiple?

When two numbers are relatively prime, then one number has to be multiplied by another to get their least common multiple.

### Why prime and composite numbers help with math?

You can use prime numbers to factorize numbers, a very useful tool

### How will identifying prime and composite numbers help you with math?

You can use prime numbers to factorize numbers, a very useful tool.

### What do you do to find the LCM when there is no multiple the same?

For any non-zero whole numbers, there are ALWAYS multiples that are the same. That's the whole point in finding the least common multiple! For example, simply by multiplying the two numbers, you get a common multiple. However, there is no guarantee that it will be the LEAST common multiple. On the other hand, writing down lots of multiples and looking for common multiples is not very efficient, except perhaps for very low numbers. A better method is to factor each of the numbers into prime factors, then use any prime factor that appears in one or more of the numbers for your result. Use the highest power. For example, if one number has a factor of 2 to the power 3, and the other has 2 to the power 2, use 2 to the power 3. Multiplying all those prime factors together gives you the least common multiple.

### What is a diagram used to identify the prime factors of a number?

A factor tree is very useful when identifying the prime factors of a number. You draw two lines off of it and write two numbers that multiply together to make that number. If one of the numbers cannot be divided any further, then circle it. That is a prime number. Draw two lines off of numbers that can be divided further, so you have multiple branches dividing off into certain numbers. Once all the numbers have been divided down, you are left with prime numbers which you can then multiply to get back to the original number.

### What does prime number mean in maths?

With math, numbers is a very interesting concept. There are different types of numbers such as prime number, composite number and so on. The concept of prime numbers is explained below which is included in the study of maths and numbers. A prime number is a number that has no factors besides the number one and itself! for example: 3 no numbers go into it except 3 and 1 The prime numbers are the numbers which are divided by the number itself and 1.1 is not a prime numbers and 2 is the only even number.To know about the prime numbers in math you can see the below link as i get some thing good explanation about the prime numbers.

### How do you use prime numbers in real life?

Data encryption, used for personal identification numbers (PINs) and for secure communications over the internet are based on very large prime numbers.

### What is Prime Factorization used for?

It allows you to find all the factors of a number. Prime factorisation is necessary for calculating the greatest common factor and least common multiple of sets of numbers. That information is essential for working with rational numbers.

### Why are prime numbers more useful than composite numbers in cryptography?

This question is based on a misunderstanding. Most cryptography is based on numbers that are products of two very large prime numbers. Being the product of two primes means that these numbers are composite - not prime!

### Is there an infinite amount of prime numbers?

Yes, as far as we know. It is very hard to prove this wrong or right, but there are prime numbers that have been found with billions of digits.yes, because there are infant composite numbers and prime will pop up Evey one in a while
