The common factors are: 1, 5, 11, 55
The common factors are: 1, 2, 5, 10
30
As a product of its prime factors: 5*7*11*13 = 5005 and so there are only 4 prime factors and not 6
the least common factors that 165 and 330 share are 1,5,14,35, and 70.
For small numbers which we can factorize easily, it is practical to use prime factorizations to find the greatest common factor. For larger numbers, however, this is not always practical. So instead we use the Euclidean Algorithm, as follows. (Here, * means multiply.) 330495 = 400 * 825 + 495 825 = 1 * 495 + 330 495 = 1 * 330 + 165 330 = 2 * 165 + 0 At each step, we divide one number by the other and get a remainder. (So when 330495 is divided by 825 the remainder is 495, etc). So we get the sequence 330495 , 825 , 495 , 330 , 165 , 0. Every common factor of 330495 and 825 is also a factor of 495, and every common factor of 825 and 495 is also a factor of 330495. Therefore the common factors of 330495 and 825 are precisely the common factors of 825 and 495. Similarly, the common factors of 825 and 495 are precisely the common factors of 495 and 330; and the common factors of 495 and 330 are precisely the common factors of 330 and 165; and these are precisely the factors of 165. In short, the common factors of the original two numbers are the factors of 165 (including 165 itself) and no others.

The factors of 330 are: 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330.
Least common multiple of 165 and 330 is 330.
330 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 330 are 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, and 330.The factor pairs of 330 are 1 x 330, 2 x 165, 3 x 110, 5 x 66, 6 x 55, 10 x 33, 11 x 30, and 15 x 22.The proper factors of 330 are 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, and 165 or,if the definition you are using excludes 1, they are 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, and 165.The prime factors of 330 are 2, 3, 5, and 11.The distinct prime factors (listing each prime factor only once) of 330 are also 2, 3, 5, and 11.The prime factorization of 330 is 2 x 3 x 5 x 11.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 , so be aware of bananas!
1, 3, 5, 11, 15, 33, 55, 165
3 * 5 * 2 * 11 = 330
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 220 and 330, we first list the factors of each number: 220 (1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220) and 330 (1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330). The common factors of 220 and 330 are 1, 2, 5, 10, 11, and 55. Therefore, the greatest common factor of 220 and 330 is 55.
