What are the factors and prime factors of 340?

Answer 1

340 is a composite number because it has factors other than 1 and itself. It is not a Prime number.

The 12 factors of 340 are 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, and 340.

The proper factors of 340 are 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, and 170 or,

if the definition you are using excludes 1, they are 2, 4, 5, 10, 17, 20, 34, 68, 85, and 170.

The prime factors of 340 are 2, 2, 5, and 17. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.

The 3 distinct prime factors (listing each prime factor only once) of 340 are 2, 5, and 17.

The prime factorization of 340 is 2 x 2 x 5 x 17 or, in index form (in other words, using exponents), 22 x 5 x 17.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
