do the prime factorization of the 3 numbers. list the prime factors of all the 3 numbers. circle the factors that are common to the 3. multiply them. that number is the HCF

All numbers can be multiplied that way. A prime number is one that can only be divided by one and itself.

What is the easiest way to figure out if numbers are prime or composite?
A prime number is one that is only divisible by 1 and itself. Just work out if it divides into anything. To do this try dividing the number by all prime numbers under its half way value.

How many times does zero appear in the whole numbers one to one hundred?
eleven, if you list numbers as 1,2,3,4,5 ect. rather than 01,02,03,04. If you list numbers the second way, then you have 20
How is prime numbers written?
prime number means the number which is obtained by multiplying the divisor by only one way. ex.5 is a prime no. 5 is obtained only in one way..ie.1*5
Will the product of any prime numbers greater than one but less than twenty ever be prime?
No. If you multiply two prime numbers, any prime numbers, the result will - by definition - not be a prime number. For example, if you multiply 2 x 3, the result will obviously be divisible by 2 and by 3, and therefore, not be a prime number. By the way, one is not usually considered a prime number.
What two prime numbers add together to make 97?
The only way two prime numbers add up to an odd number is if one of them is 2. Since 95 isn't prime, there is no solution.
