What number has factors of 2 and 3 and multiples of 12 and 18?
6, because 3*2=6 and 6*2=12 and 3*6=18
What is the probability of rolling a composite number with one roll of a die?
A composte number is any number that is not prime. The numbers 1, 2, 3, 4, 5 and 6 appear on a die. 2, 3 and 5 are prime numbers; and one 1 is niether prime nor composite (unit). Therefore, 4 and 6 are composite. So the probability or rolling a composite number is 1/3 (2/6).
What number comes next after 3 6 12 6 12 24 18?
36
What is the LCM of 3 4 6?
LCM of 4, 6, and 3 is 12, which is the multiple of the highest power of prime factors in the given numbers (22 x 3).
What is the average of 6 12 10 4 3?
The mean average is (6+12+10+4+3)÷5 = 7 The median average is middle number of {3, 4, 6, 10, 12} = 6 There is no mode average as every number appears with the same frequency (of 1).
Why is 24 not a prime number?
24 is not a prime number because is is divisible by 2 and 3. 24/2 = 12, then 12/2 = 6, and 6/ 2 = 3. 2 and 3 are primes.
What is the answer 12 prime o composite?
12 is not a prime number because it is a whole number that can be divided equally by 1, 2, 3, 4, 6, 12. So 12 is a composite number.
Is 3 11 12 prime numbers?
no. 3 and 11 are prime numbers. 12 is not a prime number as it can be divided by other things apart from itself and one. these other numbers are 3, 4, 6 and 2.
What is expressing a composite number as the product of prime numbers?
Every number can be broken down to prime factors which when times together equal your original number.12=3*2*2 How did I work that out? Well 6*2=12. 2 is prime so I can ignore it for now. 6= 2*3. 2 and 3 are also prime so I can stop. So the prime numbers that I got were 2,2,3. To check if this is right I can times them together to see what they equal. 2*2=4 4*3=12 Therefore 12=2*2*3 or 12= 2squared*3Another example for you;54=9*6. 9=3*3. 6=2*354=2*3*3*3
What is the prime number of 6?
well, the factors of 6 are: 3,2,1, and 6 and the prime factors are 3 and 2 and 6 is not a prime number, it is composite
Why is 12 not a prime number?
Prime numbers are those that can only be divided by themselves(in this case 12) and 1, but 12 is also divisible by 6, 4, 3 and 2.
What are the prime factors of 6 and 12?
The prime factors of 12 are 2 x 2 x 3. The prime factors of 15 are 3 x 5.
What are the common factors of 3 12 24?
3 is prime number otherwise 12 has 1 12 2 3 4 6 24 has 1 24 2 12 3 8 4 6
What is the probability of getting a six then a prime number?
The probability of rolling a six and then a prime on a die is (1 in 6) times (3 in 6), which is (3 in 12), which is (1 in 4), or 0.25
Is twelve a prime?
12 is NOT classified as a prime number. It is divisible by more than 1 and itself, (1, 2, 3, 4, 6, and 12), and that makes it composite, not prime.
How do you find the prime factorization of any number?
Prime Factorization "Prime Factorization" is finding which prime numbers you need to multiply together to get the original number. Example 1 What are the prime factors of 12? It is best to start working from the smallest prime number, which is 2, so let's check: 12 ÷ 2 = 6 But 6 is not a prime number, so we need to factor it further: 6 ÷ 2 = 3 And 3 is a prime number, so: 12 = 2 × 2 × 3 As you can see, every factor is a prime number, so the answer must be right - the prime factorization of 12 is 2 × 2 × 3, which can also be written as 22 × 3 Example 2 What is the prime factorization of 147? Can we divide 147 evenly by 2? No, so we should try the next prime number, 3: 147 ÷ 3 = 49 Then we try factoring 49, and find that 7 is the smallest prime number that works: 49 ÷ 7 = 7 And that is as far as we need to go, because all the factors are prime numbers. 147 = 3 × 7 × 7 = 3 × 72
Is the number 24 prime?
No because it is divisible by 2 3 4 6 8 12
