Numbers with exactly 7 factors are of the form pqr, where p, q, and r are distinct prime numbers. To find numbers with 7 factors, you need to look for numbers that can be expressed as the product of three different prime numbers.
There are an infinite number of integers with "only 7 factors". Any number which is the product of exactly 7 prime numbers.
Numbers with exactly three factors are squares of prime numbers.
Squares of prime numbers have exactly three factors.
All numbers that are the square of primes have exactly 3 factors.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
1, 2, 3, 5, and 7
Numbers with exactly 6 factors are perfect squares of prime numbers. The prime factorization of a number with exactly 6 factors is in the form ( p^2 ), where ( p ) is a prime number. There are 10 prime numbers less than 30: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. So, there are 10 numbers less than 30 that have exactly 6 factors.
Prime numbers are the numbers that have exactly two factors.Prime numbers have only two factors, the number one and themselves.
Prime numbers have exactly two factors.All prime numbers have only 2 factors whereas composite numbers have more than 2 factors
