prime because 4.5 yards equals 13 feet and 13 is prime because theres no number you can multiply to get 13 that isnt 1 and itself
1 is neither prime nor composite because Eratosthenes decided that it was nor prime nor composite because 1x1 is 1, but then again,1x any other number is that number, so one can go into every number before and after infinity. Confusing right? Try looking up on Wiki the guy Eratosthenes.
Infinity is not a number. It cannot be graphed nor placed onto a number line. Infinity is an idea, a prospect. So the answer is "none" since Infinity isnt a number.
because this number is not divisible by 2
39 is not a prime number because it has four factors: 1,3,13,39 and because prime number are numbers who has 2 factors.
9 times 11 is 99. A prime is a number whose factors are one and itself.
no, 5 isnt divisable by 19. 19 is a prime number and isnt divisable by anything.
a prime number is a number that can only be divided by 1and its self... 1 isnt a prime number but 2, 3, 5, 7, 9, 11 etc... are prime numbers.
23, 37, 79 and 51 (assuming 1851 is a typo, 18 isnt a prime) if not a typo 1851 isnt a prime number anyway, it divides by 3
