How do you find primes?
To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).

What are the prime factors of the number 20?
Prime factors of 20 : 2×2, 5 In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly. The prime factorization of a positive integer is a list of the integer’s prime factors, together with their multiplicities; the process of determining these factors is called integer factorization.
What are the factors of the number 75?
In other words, the factors of 75 are the numbers that divide the number 75 exactly without leaving any remainder. As the number 75 is a composite number, it has many factors other than one and the number itself. Thus, the factors of 75 are 1, 3, 5, 15, 25 and 75.
What’s the best way to do prime factorization?
Another common way to conduct prime factorization is referred to as prime decomposition, and can involve the use of a factor tree. Creating a factor tree involves breaking up the composite number into factors of the composite number, until all of the numbers are prime.
