## How do you find the multiples of 2 and 3?

We know that all even numbers are multiples of 2 and the sum of digits of a number is divisible by 3 are the multiples of 3. Therefore, 12, 36, 18, and 24 are the multiples of 2 and 3 both.

## Is a multiple of 2 and 3 that is prime?

Any number greater than 2 which is a multiple of 2 is not a prime, since it has at least three divisors: 1 , 2 , and itself. Any number greater than 3 which is a multiple of 3 is not a prime, since it has 1 , 3 and itself as divisors. (For example, 303 is not prime, since 303÷3=101 .)

**Are multiples of 6 a multiple of 2 and 3?**

All the multiples of 6 are multiples of both 2 and 3. 24 is a multiple of 2 and 3. A multiple can be the common multiple of two or more numbers. Example: 100 is the common multiple of 2, 4, 5, 10, 20, 25, and 50.

**What are the first 3 common multiples of 2 3 and 9?**

The lowest multiple they have in common is the LCM.

- 2: 2,4,6,8,10,12,14,16,18,20,22…
- 3: 3,6,9,12,15,18,21,24…
- 9: 9,18,27…
- 9: 3×3.

### What is the LCM of 2/3 and 4?

12

What is the LCM of 2, 3, and 4? Answer: LCM of 2, 3, and 4 is 12.

### Are all multiples of 3 prime?

Explanation: A multiple of the prime number 3 is not also a prime number because since it is a multiple, it is something like 3 × n for any number n . For example, 6 is a multiple of 3 and it is composite, not prime.

**What are the factors of 2 and 3?**

A prime factor of a number is just a factor of that number that is also prime. So, 12 has six factors — 1, 2, 3, 4, 6, and 12 — but only two of them (2 and 3) are prime, so it has only two prime factors.

**What are five multiples of 3?**

The first five multiples of 3 are 3, 6, 9, 12, and 15. Hence, the sum of first five multiples of 3 is 45.

#### What are the common multiples of 2 3 and 9?

The LCM of 2,3,9 2 , 3 , 9 is 2⋅3⋅3=18 2 ⋅ 3 ⋅ 3 = 18 .

#### Which of the following is multiple of 2 3 and 9?

List the multiples of 2,3 and 9. The lowest multiple they have in common is the LCM. 2: 2,4,6,8,10,12,14,16,18,20,22… 3: 3,6,9,12,15,18,21,24…
