How do you create a highly composite number?
A highly composite number is a positive integer with more divisors than any smaller positive integer. In other words, if τ(n) denotes the number of divisors of n, then n is highly composite if τ(m) < τ(n) for all m < n.
Is 360 a highly composite number?
360 is a highly composite number. Not only is 360 highly composite, but it is also one of only 7 numbers such that no number less than twice as much has more divisors; the others are 1, 2, 6, 12, 60, and 2520.
What is a prime number Grade 5?
Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.
Which of the following is the smallest odd composite number * 5 21 9 15?

What is the smallest composite number?
4
4 is the smallest composite number. Each composite number can be written as a product of two or more primes.. Composite numbers are divisible by other composite numbers. All composite numbers are always divisible by 1 and the number itself.
How many composite numbers are there?
Ans: There are 34 composite numbers between 1 to 50 which are as follows: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50.
What is the smallest composite number greater than 10?
4, 6, 8, 9, and 10 are the first few composite numbers.
Why is 5 a composite number?
A prime number has only two factors, 1 and the number itself, whereas, a composite number has more than two factors. For example, 5 has only two factors, 1 and 5, so it is a prime number. Whereas 6 has four factors, 1, 2, 3, and 6, so it is a composite number.
