    The answer to GCF is 2 because it is the greatest number that both 6 and 8 can be divide evenly by. 6/2=3 and 8/2=4.

    The answer to LCD is 24 because it is the smallest number that both 6 and 8 are factors of. 6 x 4=24 and 8 x 3=24 also.

    The LCM is when two numbers have the same number when they are mult. by two.
    The GCF is the biggest number that goes into those two numbers.
    EX. 8= 8, 16, 24
    6= 6, 12, 18, 24
    The Answer is “24”

    The GCF is the greatest common factore, which is the highest number, and when multiplied, equals the given number. The LCM is the least common multiple, which is the lowest common multiple of the given number.
    GCF Ex. Greatest Common Factor=2
    LCM Ex. Least Common Multiple=24

    The GCF is the largest factor that two or more numbers share. The LCM is the least common multiple of two or more numbers.
    GCF ex. 6= 1,2,3,6
    8= 1,2,4,8
    GCF is 2
    LCM ex. 6= 6,18,24
    8= 8,16,24
    LCM is 24
