The least common multiple of the numbers 84 and 54 is 756.
The least common multiple of the numbers 54 and 132 is 1,188.
Short answer: There is none. There is not a least common multiple of a single number, such as 54, because there cannot be any form of common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common multiple. The lowest common multiple of 54 depends upon the other number(s) with which it has COMMON multiples and is one of the multiples of 54. The common multiples of 54 depends upon the other numbers with which 54 has COMMON multiples and are the multiples of the least common multiples between 54 and the other number(s).
The least common multiple of the numbers 54 and 532 is 14,364.
You need two numbers for the answer, those two numbers being 18 and 54.
The least common multiple of 54 , 63 = 378
It is infinity but the LCM of the given three numbers is 54
The least common multiple of the numbers 18, 54 and 60 is 540.
There is no highest common multiple of any two or more numbers, for whatever multiple is stated, their LOWEST common multiple can be added to get an even higher common multiple. However, there is a highest common FACTOR (HCF) which is the largest positive number that divides all the numbers without a remainder, and a LOWEST common multiple (LCM) which is the smallest number into which all the numbers divide without a remainder. For 108, 54, 90: hcf(108, 54, 90) = 18 lcm(108, 54, 90) = 540
The least common multiple of the numbers 54, 63 and 108 is 756.
Least common multiple of 6 and 54 is 54.
The least common multiple of the numbers 54, 81 and 135 is 810.
