15x21=315
3
the lowest common multiple for 9 and 15 is 45
60 is the lowest common multiple of 20 and 15.
A lowest common multiple is used to compare two or more numbers. A single number cannot have a lowest common multiple.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
The LCM of the given two numbers is 2730
The lowest common multiple (LCM) is: 60
6 and 5 3 and 10 2 and 15
15.
The lowest common multiple of 15 and 18 is 90
the lowest common multiple is 75
The highest common multiple of two numbers is their least common multiple (LCM). The LCM of 3 and 5 is found by multiplying the two numbers and dividing by their greatest common divisor (GCD). In this case, the LCM of 3 and 5 is 15, as 3 * 5 / 1 = 15.
