94 is not prime. Its factors are 1, 2, 47, 94
1 x 94 = 94
2 x 47 = 94
it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc. All generated numbers will be guaranteed to have an odd number of prime factors.
A prime number has only two factors: 1 and the number itself. A composite number has more than two factors.
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

The way to be sure you have one of these is to take any three distinct prime numbers and multiply them. Those three prime numbers are then the only factors the product can have. An example is the number 30, which has factors of 2, 3 and 5.
Prime numbers are multiplied together in the same way as any integers may be multiplied together.
One way to explain why the number 1 is neither prime nor composite is that it has only one factor which is itself. Another way to look at it is that you can multiply 1*1*1... an infinite number of times and still get 1.
the answer is prime factorization dummies
Factors are just numbers. Multiply them the way you would any other number.
lcm of 46 and 69 = 139 an easy way to figure this out is by multiplying together the following: prime factors they have in common * prime factors that just 46 has * prime factors just 69 has.
Prime factorization is a way of writing a composite number as the product of its prime factors. The prime factors of 6 are 2 and 3. 2 x 3 is the prime factorization of 6.
