None of them.
No. To be rectangular a number must have two factors greater than 1. If it has two factors greater than 1, it cannot be prime.
Two numbers that have no common factors greater than one are considered co-prime or relatively prime. Their LCM is their product.
Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.
120
There are infinitely many prime numbers which are greater than 30.
(24) = 2 * (12)(12) = 2 * (6)(6) = 2 * 3so prime factors in ascending order are 2,2,2 and 3
3315 has four prime factors they are 3, 5, 13, and 17
According to the Fundamental Theorem of Arithmetic, there is only one way to write the prime factors of any integer which is greater than 1.
the number is 350 the factors is 175 and 2
2 factors, but a prime number has only two factors (itself and one). Note that 1 is not considered to be a prime number.
A number greater than 50 with only 2 prime factors would be a semiprime number. Semiprime numbers are products of exactly two prime numbers. An example of a semiprime number greater than 50 would be 77, which is the product of the prime numbers 7 and 11.
