The only prime numbers greater than 20 but less than 30 are: 23 and 29 because each is a positive integer that is divisible by exactly two positive integers — itself and 1, i.e., 23/23 = 1 and 23/1 = 23 and 29/29 = 1 and 29/1 = 29. The only prime numbers greater than 20 but less than 30 are: 23 and 29.

Why are 2 and 3 prime factors of 12?
Both 2 and 3 are prime factors of 12 because they are prime numbers that can be divided into 12 with nothing remaining. To find the prime factors of a number, first start by dividing the number by the smallest prime number, which is 2.
How to find number with maximum number of prime factors?
In case there are two or more numbers with the same maximum number of prime factors, find the smallest of all. Input : N = 10 Output : 6 Number of prime factor of: 1 : 0 2 : 1 3 : 1 4 : 1 5 : 1 6 : 2 7 : 1 8 : 1 9 : 1 10 : 2 6 and 10 have maximum (2) prime factor but 6 is smaller. Input : N = 40 Output : 30
What are the prime factors of an integer?
In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly. The prime factorization of a positive integer is a list of the integer’s prime factors, together with their multiplicities; the process of determining these factors is called integer factorization.
What are the prime factors of 3 and 5?
Now 3 and 5 are prime numbers. 3 and 5 are called prime factors of 15. The prime factorisation theorem, also called fundental theorem of arithmetic, states that any integer greater than 1 can be uniquely expressed as product of powers of primes saved for the order in which they are written.
