Square numbers have an odd number of factors.
Prime numbers in that range include 11, 13, 17 and 19.
Every number is a factor of itself. Doesn't even need to be whole, or even rational.
Yes.
Yes.
Any prime number only has two factors: one and the number itself.
No, the only factors of 49 are 1, 7, and 49. Therefore, 8 and 5 are not factors of 49.
That could either be "What numbers have 5 factors" or "What numbers have 2 and 5 as factors." Prime numbers to the fourth power, like 16 and 81, have 5 factors. Any multiple of 10 has 2 and 5 as a factor.
1009 is a prime number so its only factors are 1 and itself.
Yes, if one of the numbers is a multiple of the other.
Prime numbers only have one and itself as factors.
They all have only two factors: one and the number itself.
They are the numbers that have more than 2 factors in them because a prime number has only 2 factors which are itself and one
Numbers having only 2 factors are prime numbers. Their only factors are 1 and themselves. Prime numbers. The only two factors should be 1 and itself.
prime numbers are numbers that their only factors are 1 and itself.
None, 101 is a prime number and so has only 1 and itself as factors.
Prime numbers are numbers that are only divisible by 1 and itself. It only has two factors (1 and itself) Composite numbers have more than 2 factors (1 and itself). They are divisible by more than just 1 and itself.
The difference between prime and composite numbers is simple. Prime numbers have only two factors, 1 and itself. Composite numbers are divisible by more than two numbers
Yes, prime numbers have factors. A prime number has only two factors(1 and itself).
No, those are prime numbers.
Any prime number, a prime number is a number of which the only factors are it and itself.
71 is prime. Its only factors are one and itself.
