What are all the numbers less than 100 with exactly 3 factors that are prime?
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
Which numbers are not composite numbers?
Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.
List all the composite numbers less than 16 that have 4 factors?
Sure thing, honey! The only composite number less than 16 that has exactly 4 factors is 6. Why? Because its factors are 1, 2, 3, and 6. So, there you have it, just one sassy little number strutting its stuff below 16 with exactly 4 factors.
What are 3 Numbers that are less than 100 and have exactly 4 factors each?
Well, honey, let me break it down for you. The numbers you're looking for are 6 (1, 2, 3, 6), 8 (1, 2, 4, 8), and 9 (1, 3, 9). They each have exactly 4 factors, no more, no less. So there you have it, sweet cheeks.
