Would you rather find all the factors of a number or find all the prime factors of a number?
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.
How do you do prime numbers?
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
How do you check if a number is prime or a composite number?
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.
What are the prime number?
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
How is prime factorization different from finding factors of a number?
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
