What are the first composite numbers?
The first composite number is 4.
What does first factor mean when rounding?
It means to express a number as the product of its factors. Factors are either composite numbers or prime numbers (except that 0 and 1 are neither prime nor composite).
What is the smallest number divisble by the first three prime numbers and the first three composite numbers?
120
What is the smallest three digit number divisible by the first three prime number and the first number three composite numbers?
120
Why is 1 or 0 not composite or prime?
1 is not prime or composite because first, prime numbers are divisible by 1 and itself so 1 is itself and that is only one number. It is not composite because it only has one factor, itself. 0 is not prime or composite because it has an infinite number of divisors because any whole number that isn't 0 divides 0. It can't be written as two numbers so it can't be prime and for that same reason it can't even be composite.
What are the first composite numbers?
The first composite number is 4.
What does first factor mean when rounding?

What is the 4th composite number?
Composite numbers are numbers with more than 2 factors. The first composite number is 4. The next composite numbers are 6, 8, and 9. Thus, the fourth composite number is 9.
What are the 12 first composite numbers?
The first 12 composite numbers are.... 4,6,8,9,10,12,14,15,16,18,20,21,A composite number is basically any number that can go into that number, so like 15 is a composite number because 15x1=15,and then 5x3=15. That's two or more pair of numbers.
Can a prime number be a factor of a composite number?
yes because 2,3,5,7,11,13,17,19,23,29 are the first 10 prime numbers so if i say list factors of 12 2 is one
What is the first 4 composite numbers that have 4 as a factor?
They are: 4, 8, 12 and 16
What is the smallest number divisible by the first three prime numbers and the first three composite numbers explain?
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
What is the smallest number divisble by the first three prime numbers and the first three composite numbers?
120
What is the sum of the first four composite numbers?
You can figure out the "composite numbers" from any table of primes - all the positive integers that are not prime numbers are composite (the number one should also be excluded). The first four composite numbers are:4, 6, 8, 9
How do you notice that it is factors or prime or composite numbers?
First of all, every number is a factor - of its multiples.There is no general way to distinguish between prime and composite numbers. At one level, though, there are some simple ways. If the number is not 2, but ends in 0, 2, 4, 6 or 8 then it is a composite, If the number is not 5 but ends in 0 or 5 it is composite. If the number is not 3 but the sum of all the digits of a number is 3 or divisible by 3, then it is composite. There are moderately complicated divisibility rules for 7 and 11. But this method does not identify all composite numbers and there is no guaranteed method.
What is the smallest three-digit number divisible by the first three prime numbers and the first three composite numbers?
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
What are all the composite numbers in the world?
Composite numbers in the world are positive integer numbers that are divisible by at least one positive divisor other than itself and the number one. A composite number cannot be a prime number. The first 10 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, and 18.
