The LCM refers to whole numbers and you need at least two of them.

The LCM refers to whole numbers, not fractions.
To find the least common denominator of 1/3 and 1/4, we need to determine the smallest multiple that both denominators (3 and 4) have in common. The least common denominator is the least common multiple (LCM) of the denominators. The LCM of 3 and 4 is 12, so the least common denominator of 1/3 and 1/4 is 12.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
1/3+1/4 In order to solve a math problem with different denominators(the bottom digit of a fraction) you first must change both fractions to have the same denominator. In order to find the same denominator, you must find what is known as the least common multiple of each denominator. The least common multiple of 3 and 4 is twelve. So you must multiply each fraction to get the denominator the same. 4/12+3/12= 7/12
2 x 33 = 54 That's one number. You need at least two to find an LCM.

One way to solve this is to find the least common multiple of two of the numbers, and then find the least common multiple of that result with the third number. The least common multiple of two numbers is their product divided by their greatest common factor.The greatest common factor of 10 and 16 is 2, so the least common multiple is 10 x 16 ÷ 2 = 80.The greatest common factor of 80 and 24 is 8, so the least common multiple is 80 x 24 ÷ 8 = 240.The least common multiple of 10, 16, and 24 is 240.Another way to solve this is to find the prime factors of each number, then choose the highest power of each factor and multiply them together.The prime factors of 10 are 2 and 5.The prime factors of 16 are 2, 2, 2, and 2, which is 24.The prime factors of 24 are 2, 2, 2, and 3, which is 23 and 3.The highest power of 2 is 24, the highest power of 3 is 3, and the highest power of 5 is 5. So, the least common multiple is 24 x 3 x 5 = 16 x 3 x 5 = 240.

The first common multiple is 18. (9*2=18, 6*3=18) (9*3=27, 27/6 is a fraction) The second common multiple is 36. (9*4=36, 6*6=36) (9*5=45, 45/6 is a fraction) The third common multiple is 54. (9*6=54, 6*9=54)
One way to solve this is to find the least common multiple of two of the numbers, and then find the least common multiple of that result with the third number. The least common multiple of two numbers is their product divided by their greatest common factor.The greatest common factor of 10 and 14 is 2, so the least common multiple is 10 x 14 ÷ 2 = 70.The greatest common factor of 70 and 55 is 5, so the least common multiple is 70 x 55 ÷ 5 = 770.The least common multiple of 10, 14, and 55 is 770.Another way to solve this is to find the prime factors of each number, then choose the highest power of each factor and multiply them together.The prime factors of 10 are 2 and 5.The prime factors of 14 are 2 and 7.The prime factors of 55 are 5 and 11.Among the prime factors of the three numbers, the highest power of 2 is 2, the highest power of 5 is 5, the highest power of 7 is 7, and the highest power of 11 is 11. So, the least common multiple of 10, 14, and 55 is 2 x 5 x 7 x 11 = 770.
The first common multiple of 4, 5, and 10 is their least common multiple (LCM), which is the smallest number that is a multiple of all three numbers. The LCM of 4, 5, and 10 is 20. The next common multiple would be the next multiple of 20, which is 40. The third common multiple would be the next multiple of 20, which is 60.
