Which number from ten to twenty has an odd number of factors?
Only perfect squares can have an odd number of factors. The answer is 16. It has five factors: 1,2,4,8,16.
From zero to 16 is all the odd numbers the sum of even numbers?
If this question means "in the interval 0 to 16 inclusive, is the sum of the odd numbers the same as the sum of the even numbers ?" then the answer is no. The sum of the even numbers is eight more than the sum of the odd ones.
What is the sum of the first 4 odd numbers?
16.
What is the HCF of 20 16?
To find the hcf, first split the numbers into their prime factors: 20 = 2x2x5 16 = 2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have 2 and 2 as prime factors. Multiply these together and you get 4. Thus the hcf of 20 and 16 is 4.

Squares of even numbers like 4 and 16.
Numbers that have an odd number of factors are?
Perfect squares ( also called square numbers) have an odd number of factors and primes squared have 3 factors. Brief Explanation: If you start with a prime number, it has 2 factors by definition. Square that number and you have 3 factors, which is an odd number. So primes squared always have an odd number of factors. For example, 5 has 1 and 5 as factors, 25 has 1,5, and 25. What about an odd number such as 21 which is not the square of a prime. It has factors 1, 21, 3 and 7 so an even number of factors. How about 27, 1,27, 3, 9 once again even. What I was trying to show is that factors of numbers come in pairs and so only certain numbers will have an odd number of factors. Let's look at one more perfect square that is not a prime squared. How about 16 which is 4 squared. The factors are 1,2,4,8,and 16 which is an odd number of factors. Looking at these as pairs we see the factor pairs of 16 are 1 x 16, 2 x 8, and 4 x 4, giving us the factors of 1, 2, 4, 8, and 16 - an odd number of factors. So we conclude that perfect squares have an odd number of factors and primes squared have 3 factors.
