What is the least common multiple of 12 and 30?
60
The LCM of 12 and 30 is 60. To find the LCM of 12 and 30, we need to find the multiples of 12 and 30 (multiples of 12 = 12, 24, 36, 48 . . . . 60; multiples of 30 = 30, 60, 90, 120) and choose the smallest multiple that is exactly divisible by 12 and 30, i.e., 60.
Which is the greatest factor of 27 54 81?
Each of the numbers can be divided by 1, 3, 9, and 27, so you can say that these numbers are common factors of the set of numbers 27, 54, and 81. The largest of the common factors is 27, so you can say that 27 is the greatest common factor of 27, 54, and 81. See the Factoring Calculator to learn more about finding the factors…
Which is the greatest common factor 50 or 120?
The prime factorization of 50 is 2 x 5 x 5 = 50. The prime factorization of 120 is 2 x 2 x 2 x 3 x 5 = 120. The occurrences of common prime factors of 20, 50 and 120 are 2 and 5. So the greatest common factor of 20, 50 and 120 is 2 x 5 = 10.
How to calculate the greatest common factor GCF?
Referring to the previous example, if instead the desired value were GCF (268442, 178296, 66888), after having found that GCF (268442, 178296) is 2, the next step would be to calculate GCF (66888, 2). In this particular case, it is clear that the GCF would also be 2, yielding the result of GCF (268442, 178296, 66888) = 2.
Which is the greatest common factor of 18 and 27?
The occurrences of common prime factors of 18 and 27 are 3 and 3. So the greatest common factor of 18 and 27 is 3 x 3 = 9. The prime factorization of 20 is 2 x 2 x 5 = 20. The prime factorization of 50 is 2 x 5 x 5 = 50. The prime factorization of 120 is 2 x 2 x 2 x 3 x 5 = 120.
