RafaTo find the greatest common factor (GCF) of 15, 30, and 48, we first need to find the prime factorization of each number. The prime factorization of 15 is 3 x 5, the prime factorization of 30 is 2 x 3 x 5, and the prime factorization of 48 is 2 x 2 x 2 x 2 x 3. The GCF is the product of the common prime factors raised to the smallest powers they appear in any of the numbers, which in this case is 3. Therefore, the GCF of 15, 30, and 48 is 3.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The greatest common factor of 15, 30, and 48 is 3

What are the common factors and greatest common factor of 30?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 30, 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. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. Examples: The common factors of 30 and 32 are 1 and 2; the greatest common factor is 2. The common factors of 30 and 45 are 1, 3, 5, and 15; the greatest common factor is 15. The common factors of 30 and 57 are 1 and 3; the greatest common factor is 3. The common factors of 30 and 65 are 1 and 5; the greatest common factor is 5. The common factors of 30 and 72 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 30 and 100 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 30 and 180 are 1, 2, 3, 5, 6, 10, 15, and 30; the greatest common factor is 30.
