Only one can be least. That's 66. More common multiples add 66 to that.
66, 132, 198, 264, 330
The least common multiples of 5, 11, and 13 is 715.
The first step is to find the least common multiple of 5 and 11. The least common multiple of two numbers is to multiply them together and divide by their greatest common factor. The greatest common factor of 5 and 11 is 1, so the least common multiple is 5 x 11 ÷ 1 = 55.Next, to find common multiples 5 and 11, list the multiples of the least common multiple.55 x 1 = 5555 x 2 = 11055 x 3 = 16555 x 4 = 22055 x 5 = 275
The Least Common Multiple (LCM) for 5 and 8 is 40.
