The GCF and LCM of 18 and 27 are 9 and 54 respectively.

GCF is the greatest common factor . The factors of 18 are 1, 2, 3, 6, 9, and 18.

The factors of 27 are 1, 3, 9, and 27.

Therefore the GCF for 18 and 27 would be 9.

The LCM is the smallest multiple.

Multiples of 18 are 18, 36, 54, 72, 90, 108, 126, 144, and so on.

Multiples of 27 are 27, 54, 81, and so on.

The first matching number is 54 (18x3 or 27x2).

Therefore the LCM for 18 and 27 is 54.

The GCF of 6, 18, and 27 is 3.

The prime factorization of 6 is 2*3.

The prime factorization of 18 is 2*3*3

The prime factorization of 27 is 3*3*3

So the GCF is 3.

What are the greatest common factors of 18 and 36?

18 is the greatest common factor.


What are the common factors and greatest common factor of 18?

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 18, 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 18 are 1, 2, 3, 6, 9, and 18. Examples: The common factors of 18 and 24 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 18 and 54 are 1, 2, 3, 6, 9, and 18; the greatest common factor is 18.


What is the greatest common factor of 18 and 90?

Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.Since 18 is a factor of 90, it is automatically the GCF.

What is the greatest common factor of 18 and 51?

The greatest common factor of 18 and 51 is 3.18 ÷ 3 = 651 ÷ 3 = 17Method: One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 51 are 1, 3, 17, and 51.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 51 are 3 and 17.The prime factors in common are a single 3, so the greatest common factor is 3.The greatest common factor of 51 and 18 is 3
