How do you use prime factorization to find the GCF of three numbers?
You can find the prime factors of all three numbers, combine (multiply) those numbers and remove redundant factors. So if your numbers are 4, 6 and 8, then those factors are (2*2), (3*2), and (2*2*2) respectively. The GCF is 24 or (2*2*2*3). This is because 24 can be written as a multiple of all three numbers because 24 can be written as a multiple of 2 4 and 6. (2*2*3*(2)) (2*3*(4)) and (2*2*(6)). If this is still unclear you can check the Wikipedia Article on LCM.
What is the three prime numbers of 18?

What three digit number has the most factors?
Using prime factorization, there are 2 three digit numbers with 9 factors: 512 and 768. There are no three digit numbers with 10 or more prime factors. 512=2^9 and 768=3*2^8
A number that has exactly 3 factors?
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.
What r the 3 numbers that have 2 4 and 8 as factors?
Calculate the least common multiple of the three numbers. Any multiple of that has all those numbers as factors.
