Step-by-step explanation: The factors of a number are the numbers that divide evenly into the number. For example the factors of the number 12 are the numbers 1, 2, 3, 4, 6 and 12. (Notice that the smallest factor is always 1 and the biggest factor is always the number itself.)
What is a factor of 2 and 12?
The factors of 12 are 12, 6, 4, 3, 2, 1. The common factors of 2 and 12 are 2, 1, intersecting the two sets above. In the intersection factors of 2 ∩ factors of 12 the greatest element is 2. Therefore, the greatest common factor of 2 and 12 is 2.
What is the GCF of 18 and 3?

The GCF of 3 and 18 is 3.
What is the LCM for 15?
What is the LCM of 15 and 15? The LCM of 15 and 15 is 15.
What’s the GCF of 3 and 18?
How to calculate the least common multiple of 2 and 12?
We need to calculate greatest common factor 2 and 12, than apply into the LCM equation. Least common multiple can be found by multiplying the highest exponent prime factors of 2 and 12. First we will calculate the prime factors of 2 and 12. Prime factors of 2 are 2. Prime factorization of 2 in exponential form is: Prime factors of 12 are 2, 3.
Which is the most common factor of 12?
The factors of 12 include: 1, 2, 3, 4, 6, and 12. Thus, the common factors of 16 and 12 are: 1, 2, and 4. Often in math problems, it can be desirable to find the greatest common factor of some given numbers. In this case, the greatest common factor is 4.
What are the least common multiples of 6 and 12?
Least common multiple (LCM) of 6 and 12 is 12. LCM(6,12) = 12. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
What are the common factors of 16 and 12?
Thus, the common factors of 16 and 12 are: 1, 2, and 4. Often in math problems, it can be desirable to find the greatest common factor of some given numbers. In this case, the greatest common factor is 4. This calculator only accepts positive integers as input to calculate their common factors.
