Is 23 prime or composite yes or no?
Yes, 23 is a prime number. The number 23 is divisible only by 1 and the number itself. For a number to be classified as a prime number, it should have exactly two factors. Since 23 has exactly two factors, i.e. 1 and 23, it is a prime number.
Is 46 a prime number or a composite number?
Is 46 a prime number? “No, 46 is not a prime number.” Since 46 has more than 2 factors i.e. 1, 2, 23, 46, it is a composite number.
Is 46 a composite number?
46 is a composite number.
Is 13 and 23 a prime number?
The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.
What is the composite of 23?

What are composite factors of 46?
Thus, all the factors of 46, including both prime and composite numbers, can be written as 1, 2, 23, and 46.
Is 46 a rational number?
46 is a rational number because it can be expressed as the quotient of two integers: 46 ÷ 1.
What is the prime factor of 46?
2 and 23 are the prime factors of 46.
Which of the following is composite?
The first few composite numbers (sometimes called “composites” for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, (OEIS A002808), whose prime decompositions are summarized in the following table. Note that the number 1 is a special case which is considered to be neither composite nor prime.
What makes a composite number?
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.
Is the number 3×5×13×46+23 prime or composite?
Explain whether the number 3×5×13×46+23 is a prime number or a composite number… See what the community says and unlock a badge. It is a composite number. Let’s see if we can simplify the expression by getting rid of the plus sign.
Why is 3 a prime number but not 1?
A prime number is the one which has exactly two factors, which means, it can be divided by only “1” and itself. But “1” is not a prime number. 3 is a prime number because 3 can be divided by only two number’s i.e. 1 and 3 itself.
What are all the prime numbers less than 30?
The prime numbers less than 30 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. By the definition of what a prime number is, one (1) is NOT a prime number because it is exactly divisible by only ONE positive integer — just itself, thus 1 does not fulfill the necessary “exactly TWO-positive integers” requirement in order to be prime.
What is the difference between a prime number and composite number?
A prime number is a number which has exactly two factors i.e. ‘1’ and the number itself. A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number. We don’t consider the number ‘1’ as a composite number.
