To find two numbers that multiply to 310, we need to factorize 310 into its prime factors. 310 = 2 * 5 * 31. Therefore, the two numbers that multiply to 310 are 2 and 155, as 2 * 155 = 310.
The factors of 310 are 1, 2, 5, 10, 31, 62, 155 and 310.
Answer:310 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0, 2, 4, 6, or 8 is evenly divisible by 2, so it has 2 as a factor. 310 is also divisible by 2, so it is a composite number.
