You need at least two numbers to find an LCM.
There is an infinite number of common multiples for 13 and 81. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple of 13 and 81 is 1,053.
They are all multiples.
You need at least two numbers to find an LCM. The multiples of 9 between 70 and 105 are 72, 81, 90 and 99.
Assuming that least common refers to the least common multiple, LCM(27, 81) = 81
81, 162, 243 and so on.
1, 3 and 9 are common factors of 27, 45 and 81. 27, 45 and 81 are multiples of 1, 3 and 9.
The Least Common Multiple of 9 and 81 is 81.
Common multiples include any multiple of 405.
52 = 4 x 13 = 22 x 1381 = 9 x 9 = 34Since 52 and 81 do not have any common prime factor, then 52 x 81 = 4,212 is their LCM. So that the other multiples they have in common are all the multiples of 4,212.
Least common multiples 12 and 16 is 48.
The least common multiples of 7 and 14 are 14,28 and 42>
The least common multiples of the number 6 and 9 is 3.
