Which is a prime number with no remainder?
Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29… 90 ÷ 2 = 45 – No remainder! 2 is one of the factors! 45 ÷ 2 = 22.5 – There is a remainder. We can’t divide by 2 evenly anymore. Let’s try the next prime number 45 ÷ 3 = 15 – No remainder! 3 is one of the factors! 15 ÷ 3 = 5 – No remainder! 3 is one of the factors!
What are the prime factors of an integer?
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.
