690 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, and 690.The factor pairs of 690 are 1 x 690, 2 x 345, 3 x 230, 5 x 138, 6 x 115, 10 x 69, 15 x 46, and 23 x 30.The proper factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, and 345 or,if the definition you are using excludes 1, they are 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, and 345.The prime factors of 690 are 2, 3, 5, and 23.The 4 distinct prime factors (listing each prime factor only once) of 690 are 2, 3, 5, and 23.The prime factorization of 690 is 2 x 3 x 5 x 23.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.
There is neither a greatest common factor nor common factors of a single number, such as 345, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
