15 is a factor of 30 and 60. Since 15 is also the largest possible factor of itself, the greatest common factor is 15.

Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.

The factors of 15 are 1, 3, 5, and 15.

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

The common factors are 1, 3, 5, and 15. Therefore, 15 is the greatest common factor.

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.

The prime factors of 15 are 3 and 5.

The prime factors of 30 are 2, 3, and 5.

The prime factors of 60 are 2, 2, 3, and 5.

The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.

The greatest common factor (GCF) of 15, 30, and 60 is 15. To find the GCF, you need to identify the factors of each number. The factors of 15 are 1, 3, 5, and 15. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The largest number that is common among all three sets of factors is 15, making it the greatest common factor.

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.
