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.


What is the greatest common factor of 30 and 64?

The GCF of 30 and 64 is 2. The factors of 30 are 1,2,3,10,15, and 30. The factors of 64 are 1,2,4,8,16,32, and 64. The greatest common factor of 30 and 64 is 2.


What is the greatest common factor of 60 and 40?

The GCF of 40 and 60 is 20 Additional Details The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common factors are 1, 2, 4, 5, 10, and 20. Therefore, 20 is the greatest common factor. The greatest common factor can also be determined from the prime factors. The prime factors of 40 are 2, 2, 2, and 5. The prime factors of 60 are 2, 2, 3, and 5. The prime factors they have in common are 2, 2, and 5, so the greatest common factor is 2 x 2 x 5 = 20.
